I really enjoy my new HID headlight kit but during the installation I had a small problem, one of the high beams wasn't working. This video shows the process I went through in order to determine the cause of this failure. HID's can be 'delicate' so you may need to use this information at some point. My friends at Motorfiend were more than willing to send me some new parts so that I could complete the repair.

Eric makes it so very simple...Thanks Eric from an old retired Army guy thanks for your service via Repairs to this old guy & many others.

@hollowdog7208 8 лет назад

Not my first thinking for the fix but as always a excellent way for the novice to cure a problem. Enjoy all of your videos. Your the best!

eric you are awesome. i love the simple diagnostics you use. so helpful to dummies like me haha. appreciated.

@mechguy83 11 лет назад

Short and simple and to the point, I like the way he approached this. Besides I don't think the average D.Y.I owns a oscilloscope and they (average joe) is truly who he makes these videos for.

@sergiocabrales980 5 лет назад

Thank you Eric for you information.

@slrr123 11 лет назад

Eric just to ensure no confusion on this, there is only two components for Bi-Xenon kit. The bulbs have a coil with a magnet in it. The third connector with the two wires in it energize the coil to move the bulb for the high beam position. Now the two things you will need to look at is the bulb (swap them like you did) if it moves then you are good. If not then you need to look at the relay kit. The ballast only powers the bulb. I install and troubleshoot these things for a living.

@hairychesticles1 3 года назад

Thanks for the vid even 6 years later. I have a 2015 challenger and right now one of my HIDs is intermittently not working so sadly im not sure what it is but hopefully i will find out soon

@Cr3ativity 11 лет назад

Hey, Eric. Thanks for posting this video. HID's are definitely useful. In fact, I have 6000K HID's and I am going to be installing fog lights soon. Thanks for wishing everyone a Happy Birthday. Mine is on May 11 :D Anyways, hope you and your family are well. Cheers!

@svr27rr87 7 лет назад

Thanks you 4 the Good info video.. helps me solve problem with mine.

@garthmounce9331 10 лет назад

The ballasts have nothing to do with the function of high and low beams. The ballast just powers the bulb and make it produce light. The relay harness controls the high/low functions. It has an input from the stock plug, when you switch from low beam to high beam, a different wire on the plug is electrified and thus sends a signal through the little wires to the small connector on the bulb which charges a solenoid that pulls the bulb backwards in it's housing. When that happens, the angle of reflection inside the headlight housing changes due to the capsule of the bulb being in a different spot.

@pghguerrilla8508 6 лет назад

Garth Mounce I probably won't get a reply but I'm running out of help. No mechanic knows wtf they are doing around here. So, my hid headlights worked fine when I got the car, after a while some guy took out my drivers side headlight for reasons. Once it was put back in, it started to not work unless I turned off, then back on. Now both low beam headlights don't work (unless I keep turning on and off)and one of my fog lights are starting to not work. Can you give me some advice? I don't think it's a bad bulb because of the fact they turn on sometimes. From that can you help?

@z33tanner 6 лет назад

PGH Guerrilla HID bulbs are not like regular halogen bulbs with a filament. They can be bad and still turn on for a moment or few minutes. I had cheap kensun bulbs in my Acura TL and one would turn off after a few minutes of driving then come back on after i cycled the headlight switch. Swapped the bulbs and the problem percisted on the other side so i replaced my bulbs with some quality osram xenarx intenses and i havent had any problems. If both of your headlights are turning off at the same time i would check for good 12v power and ground to your hid ballasts. Sounds like wiring to me if your fog light recently went out too.

@z33tanner 6 лет назад

PGH Guerrilla Have you tried swapping the bulbs left/right? This would tell you easily if it is a bulb issue or not

@tomharvey7429 5 лет назад

PGH Guerrilla im going try the ballast it blows as soon as you turn them on just the drivers side like it’s getting too much juice

@jmanzella94 11 лет назад

I installed 10k on my 98 blazer. Will never use stock bulbs again. Their easy to do. And the results are insanely nice. Their bright as could be and a lot more effacted as long as you don't aim them high your good in the law

@Justindobb1984 11 лет назад

* Tip * Use tape or electric grease on all connections after you install a kit and confirmed all is working correctly even on the fuse in the wiring harness. Strangely, one huge issue I ran into was corrosion on the fuse in the wiring harness only months of installing. Hope this helps others.

@shazib1081 5 лет назад

Thanks for the video!

@Lokiavanger 11 лет назад

I had an issue when I made my retrofits where they would only stay in low beams, the dash said high beams were on, and the stalk did not change anything. It ended up being an issue with the harness and the fix was swapping two of the pins in the connector to the stock harness. Possibly something to look into if you're having an issue. :)

@josephnyoni8361 Год назад

Great video thanks can you please share a video on how to wire the circuit of the ballast lighting system

@mondeo984 11 лет назад

It converts the 12 VDC to around 80 VAC, but in order to ignite the HID it gives > 1000 V at startup. If you listen to the balast you can hear the switch mode circuit scaling up the voltage.

@zx8401ztv 11 лет назад

Smashing job, like the logical approach :-) :-)

@maxbolen27 5 лет назад

I noticed a ballast mounted directly next to the headers. The amount of heat from the headers will shorten the lifespan of the ballast. I like to place them near the light in a dry and cooler spot,

@thorlarsen9770 4 года назад

Thanks Eric same issue on my 02 WRX after installing hid LED lights, I'm thinking mine's an alternator issue because the alternator case is covered in dust from bad/worn brushes.

@frdradio 11 лет назад

Lol!! Good touch on the "if it's your bday!" Lol

@bilenpelle 11 лет назад

Cars that come with factory installed HID lights have these lenses for a reason, yes, they do blind less than converted HIDs. If you make sure you adjust your lights you won't blind other drivers, even with aftermarket lights. I know many people that have HID lights, both converted and stock, it doesn't blind me when i meet them on the roads. Neither have i had anyone flash their high beams at me for blinding them with my HIDs.

@Dcs-Brasil 11 лет назад

Good job

@AMPLIFIER942 11 лет назад

It's not my birthday but thanks Eric! I just came home from my graduation celebration party. :)

@JonathanThompson1320 11 лет назад

Dude. Thanks! I recently experienced a similar issue. A have an aftermarket HID kit. A bulb gradually went out, discolored, then just stopped. The other bulb was fine. Replaced both bulbs. Now, bulbs seem to work but they are a little off. Example, the left side will not come on. I have to turn off the headlights and turn them on, then both will be on and will stay on for the duration of the drive. I suspect the ballasts are now the problem. Your thoughts?

@MrGhOsT4273 6 лет назад

ok got one for you, i have a 1999 Ford Mustang GT and it has the LED with Ballast and driver side not working, so i changed them both around and all lights work when its in the passenger side both will not work on drivers side at all, both lights and stuff are good. and also if i turn my brights on both sides work.

I went back to your original install video, and it looks like high beam did work at at that time at least when you first turned it on. It is little worrisome that it stopped working s soon.

@guitartec 9 лет назад

Notice the highs aren't any brighter than the lows? They just seem to redirect the beams focus higher up. Mine do that too.

@francistheodorecatte 11 лет назад

automotive HID ballasts have to generate the high voltage needed by the lamp (usually by using a high-current switchmode inverter,) in addition to doing the current limiting, and providing an ignition circuit for the lamp. if you do some googling you're bound to find schematics, but I couldn't find any of modern (electronic) ballasts.

How do I install halo headlights while keeping my current HID bulbs?

@TonaldJDrump-dl2bu 2 года назад

i had a xenon bulb that flashed when i start the car up but would stabilize once the the engine was on for about 5 seconds, it finally went out the other day. i just got a new pair when i plugged the new bulb in it started flashing, what do you guys think the issue is?

@Irish614 4 года назад

I got a weird one here. My wife's passenger side high beam stopped working, I thought ok it must be the bulb. I ordered some new ones and they came in, I installed them and they didn't work. The driver side worked like yours in the video so I did the ballast swap but it didn't work. So I took the driver side ballast back to the original location and now neither work. I did manage to get the driver side high beam to work momentarily but it stopped working again. I've been trying to figure it out for weeks now. I even reversed polarity to see if that did the trick and nothing. The low beam still work. When the replacements arrived I just plugged them into the existing wiring and should have fired right up. Think I'm going to call it and swap them for LED's.

@mikejmardis 3 года назад

Only 3 main things? What about when you narrow it down to wiring? How many things then? Wire? Relay? Module (maybe not on this year model)?

@JustinTwilley 6 лет назад

Hey manI have hids on my bike, the other morning omw to work I noticed one of my low beams cut off. so I was like well darn need a bulb. but then I started the bike to leave work both came on I drove down the road and leaned forward to see if the light was still on and it was not. So this happened for like 3 days in a row it would come on for a few minutes and shut off, well now neither one comes on at all, I believe there are 2 ballasts so what do you believe could be my issue? My high beams work fine.

@barbaramartinich4005 3 года назад

Thank you, but I wish you would have shown how to change the ballast. If you have done a video could you please post again?

@MrRobotmarshmallo 8 лет назад

Bulbs, ballasts, battlestar galactica. You know you read that just like Jim.

@neurosync_research 6 лет назад

What kind of damage can be done if you flash your HIDs? Say turning off your hi beam HIDs for a passing car and turning them back on 30s later once the car has passed.

@numero1latina45 6 лет назад

Super cute. Tomorrow is my bday. 😁 I'm trying to diagnose a headlight on my Toyota matrix. Looks like loose wires. Any ideas? Thank you!!

@alor6643 5 лет назад

Troubleshoot with the following order: 1.grounds(*both sides or side that have problem) 2. headlight fuses(*) 3.fuse from relay harness 4.bulb(*) 5.ballasts(*) My issue was , that after 1 year the one side ground stop working like ground( no modifications).As a result of this the driver headlight doesn't turn ON.

@daveogarf 8 лет назад

Thanks, Eric! Excellent presentation.Could you tell us why you decided to switch your halogen headlights for HID? What do you consider the advantages of HID lighting?I believe that I've heard that HID is not only brighter, but more sharply focused, and allows you to see farther down the road. I'm thinking that they may last longer than their halogen counterparts.Have they improved the focus and cutoff of these enough to make them less obnoxious to oncoming vehicles? I used to see that cold white light coming, and have to avert my eyes to avoid night blindness. Haven't seen that as much lately.Again, thanks! Please keep up the excellent work.

@Valde3333 11 лет назад

You can repair high solenoid in those china bulbs, especially if they don’t work from new. Normally all it needs is one solder joint.

@Peterjohn32 11 лет назад

should check for voltage at the bulb solenoid to see if the harness is sending it power a lot quicker than pulling the bulbs out

@tannarbradley 7 лет назад

I've had a hid kit for a while now but sometimes when I leave in the morning 1 side won't turn on and I have to sit there and turn the lights on and off several times before it'll come on, and when I've been driving a while stop then start back up it'll do it again

@kelvinguevara4920 8 лет назад

hi Eric I always watch your videos, I like the concept of em, I have a question I bought a new battery for my car which i plugged wrong negative with positive, I had a little electric shock, than i unplugged it and did it the right way luckily the car started e few days after I pulled out some codes P 1684 which is it got something to do with the battery and p0455 . my car is a 2001 chrysler lhs what do you recommend me to do. thanks

@jackschoedinger391 10 лет назад

Eric, I just installed a HID kit (same brand in the video) into my '04 Silverado low beam location. Everything works well, except...My HID's are coming on during the day with my DRL's (Daytime Running Lights). Do you know of a solution to keep the HID's off when my DRL's are on?

@ariesr4883 4 года назад

What are your thoughts when using a relay kit for HIDs?

@luisfranco9394 7 лет назад

Hi Eric, I drive a 2009 VW passat B6 and once I start the car the low beam starts flickering then shuts off. This happens all the time. Where do I start? I tried removing the bulb but after turning the white screw tab that releases the bulb from its housing it did not come out all the way. I stoped cuz I though it would break if I force it out. Thank you for any help. the dealer wanted $220 plus taxes just for the bulb but I really doubt that's the problem. If it was it would not light up every time I turn on the car. Thanks again for your help. Luis.

@knifeaddict1014 7 лет назад

hey how did you get the bulb out im having trouble geting my bulb out because one of my light went out and im trying to figure whats going on as well

@Ai-Galaxy-GS 9 лет назад

Hi, I have a Ford E350 09, the vehicle itself has perimeter feature, which is when unlocked by remote, all of the exterior lights would come on, even the headlights.So today I took it to the local shop and put a pair of HID on but.....even they couldn't get it to work, It worked when the engine's off, but not when it was on, first they did it without the harness, then with it , eventually it wouldn't come on at all, what do you think the problem is?

I just purchased this Extreme Lighting Accessories Kit. Dealer wanted $95 just to install and gives a 1 yr warranty with it. After hearing and seeing videos do you suggest I have this professionally installed? or should I trust a mechanic on the corner who may or not be familiar with this?

@2brosfilmz208 4 года назад

I had a set of hids on my 2015 Jeep Wrangler for about 2 month now they both stopped working at the same time, would this be a relay or fuse most likely? thanks for your time.(high and low beam don't work)

@napalmx2 10 лет назад

@robertodayso9059 8 лет назад

The HID lights will not power off /turn off on my 1999 Suzuki Sidekick even when the engine is off and the light switch is in the off position. I have to remove the power fuse to turn it off. Can you help please?

@Ak-47ram 3 года назад

My headlight stopped working after I got my windshield tinted water must've seeped through behind the dash.. does that mean its the harness that needs replaced something else?

@wanteddeadoralive8798 Год назад

Probably too late and too generic, but I have intermittent on/off conditions they both shut off at different times, I’m assuming maybe headlight switch, or both ballasts are bad? The lights work good when actually on

@wax4dadsglossking28 6 лет назад

How do you replace the actual bulb please? I can't get mine off the housing. Does metal housing on actual bulb twist off?

@spyland21 11 лет назад

Hi eric. I have same problem but it's not the bulb. I replaced them both high and low beam with new once but still doesn't work. I tried to check the fuses but I can't find the light fuse. This is what happening. When you put it to low beam, the other side has low light ( not similar light coming out), then when I change it to high beam, the side with the low light shuts off, as in it's dead. What do you recommend to do? Btw, it's a 2005 subaru impreza 2.5rs.

@Seegalgalguntijak 11 лет назад

So it's basically just a big resistor? Or does it also generate the high voltage? Do you happen to know where I can find technical schematics of it to see how it works?

@hungrynapps 10 лет назад

mines work properly . one problem .. when i now switch it on . it cuts off my mids amp .. n my fogs come on then one side cut off .. i checked all my groundings . some people say could be my battery power too low .. to run all my gadgets . 825 cranking amps .. no maintenance battery around 2yrs old

@jordansmith1626 7 лет назад

I have a morimotto ballast with Osram CBI bulbs. Lately sometimes they won't work. Sometimes one will work and sometimes both work fine. As soon as I fire them up. They stay on. But if I turn them off they might not go on again. It's the same for both sides. Is this the bulb? Grounding? Or is there something else it could be

Ive got a question, so on my bulbs ive got a 9004/9007 setup on my f150. The bulbs dont come on at all but they retract when I turn the high beams on, could that be a bulb issue? im hopsing so as they are only 20$ for two to replace

@jsomachine 7 лет назад

my fog lights hids don't turn on its a new kit that I received today. Headlight hids do work could it be a fuse?

@chrisneed1563 3 года назад

What did the bad bulb look like?

@stevealaska73 4 года назад

Wouldn't the fuse be a candidate to check as well? As of 2 days ago, I have a pass. high beam, pass. DRL, AND a pass. brake light out right now. The "DRL" dash light is on too. Im a bit nervous. Off to switch the headlight bulbs. Cross your fingers for me. Ps, I did just install a brand new battery. A few months ago, I removed the fuse for the DRLs. Replaced that back in there and it solved nothing.

@francistheodorecatte 11 лет назад

it limits the current the bulb can draw, because without it, it'd go into thermal runaway and burn out. same reason why LED's must have current limiting resistors to keep them from burning out.

@taylormordoch9802 7 лет назад

I have the same problem with my Honda PCX I just changed the bulb it's still doing the same thing I'm guessing it's a ballast.

@Seegalgalguntijak 11 лет назад

What does the ballast actually do on an HID headlight system? Obviously, it doesn't work without one, but what does it do?

@newfieledman9164 7 лет назад

hello Eric i have a problem with headlights i have HID lights with Can-Bus Ballasts the problem that i am having is the when the lights are shinning on the wall or ground it is impossible to adjust cause my head lights has a center piece that is kinda open in the center and i have noticed on the standard halogen bulb has a painted end on the bulb when they work fine but not bright enough so i decided to go with the HID and then noticed that the end of the bulb has no paint on the tip or chrome so my problem is how do i fix this the lights are shinning everywhere but cannot adjust and has big shadows on the ground and on the wall my reflector center piece has no chrome tip is there away that i can make a reflector to make the lights shine better i have 2003 Grand Am 3.4L v6

@Lagscape 11 лет назад

the problem i have is i got a car that has h.i.ds and low beams and what happens is low beams is low beam than high beam is h.i.ds but what happens is most times the h.i.ds dont work on high beam but the low beams work on high where hids should be set at and once in awhile hids work and low beam wont its annoying any ideas? thanks
