I freaked when I saw the condition of the factory wires on my 2007 BMW headlights. The insulation was falling off in chunks. I did hear this may have been some GREEN Soy based insulation??? Anyway bad supply issue to BMW and also Mini.
This had 55w globes in it and to my knowledge it always has, so it isn't due to over rated globes, this is a known issue.
Here i show you a simple fix to keep you going. I had replaced three globes prior to doing this repair. Once i did it I never blew another globe. I DO LIKE AND RECOMMEND the LIQUID electrical tape in the link below.

I used liquid electric tape following several hrs of trying ti tape as you do. Worked like a charm r

When u see one wire dry and cracked, there are others. It is not just because of heat. It is mainly the "biodegradeable" material used. The only way to fix is to open up the lens and take apart everything and pull the harness out and depin each wire to shrink wrap it. It is painful but a permanent solution.

My wife has an 05 X3 with this exact same issue. A globe blew and I pulled it out today to check which globe it was and seen all the damaged casing. How disappointing they have not done a recall..

How long will my headlights last if I buy new ones ? As in befor they start coming off like those mine are doing the same

@ezrah. 5 лет назад

hi do you know if the connector that you taped was stock or did you buy it from another place if so do you remember what they are mine are toast and only have one head light

@Marksreviewsandtutorials 3 года назад

I didn't replace any connectors. This was a std H7 globe so you can get connectors from any auto parts stores.

@techten1012 Год назад

Is yellow positve or brown? I am replacing connector with pig tail connector

@wessteenrod6838 5 лет назад

Liquid electrical tape would give a weather tight seal and a cleaner finished look than any tape.

@nickcwilliams9911 4 года назад

That is what I used as well. I took the headlamp totally out. I still have the failing bulb dash light on. Do you think the wires crossed and damage d the bulb?

@adavila78 4 года назад

@@nickcwilliams9911 I plan on going the liquid tape route my cables are the same, I have some adaptive headlights error but the light does not turn on.. maybe a fuse got damaged and it blocked the light?

@whlawson5812 Год назад

@@adavila78 I think liquid electrical tape, after drying, is best be wrapped with 3M 35 electrical conformal tape good for 210 degree F.

@waqasazam4454 6 лет назад

HI mark i have an e60 too, and have a dipped beam error, the bulb is fine but there is no power getting to the plug. the wiring looks visibly fine too, any ideas what this might be?

@Marksreviewsandtutorials 6 лет назад

Hi waqas azam because of the bad wire insulation issue I would start there and make sure there are no shorts. Other than that it is just tracing the wire back to see where there is power, starting at the fuses.

@waqasazam7727 6 лет назад

Mark's reviews and tutorials hi mark , any idea which fuse / relay would relate to the Passenger side dipped beam mate ? I’m totally stuck

Can this cause a drivetrain malfunction I have a 2009 bmw 650i convertible headlights wires are exposed and touch sometimes not sure if this can cause that

@Marksreviewsandtutorials 10 месяцев назад

I don’t believe so no. It will blow your headlight globes though.

@chesterredrum4917 10 месяцев назад

@Marksreviewsandtutorials have any ideas that can cause it I've changed my starter,head gasket, pvc values, crankshaft sensor, oil pressure sensor, I have no leaks, but one thing that got my attention is that I do have cracks right where the windshield wiper are and I'm wondering is water going down somewhere and and leaking onto a module or something is there's one in that location and sometimes it's says the key is not reading to the computer witch I don't understand because the car stills starts up before the drive trans messages, also the engine light will come on and eliminate

@seanpaul3050 10 месяцев назад

Wires shorting out will either blow a fuse or the car will detect the short and cut power to that particular bulb.

@aavaz3043 4 года назад

Yes is because of bmw headlights create a lot heat. I have the same problem but in the bottom where is hard to see it was a short because of this problem. Problem is the head light only one cost me 1,500.00 no labor.

@gregb1276 4 года назад

No, it's because BMW used wiring with faulty insulation. My 54 year old Ford truck still has the original headlight wires. Surely, BMW can do as well as old Ford trucks.

@maxheadroom1506 3 года назад

BMW should be sued for this as it is common in most of their cars. At some point they decided to go green and use SOY insulation wires which degrade and are a great snack for rats. for quick fix others have used liquid insulation that they pain on or spay on. I personally would like to find a service that will crack the headlight open replace these junk wires with normal wiring like in every other car in the world and replace the dull lens. I can not seem to find anyone doing this though. I do not want to spent $1000/new headlight that has the same crappy soy wiring in it. I also recommend for people to replace what ever they can inside these headlights with error free LEDs as they do not get as hot which will prolong the life of the plastic housing which can also crack.

@seanpaul3050 10 месяцев назад

The led’s may not get that hot. But the ballasts you have to fit to prevent error codes get very hot instead.

Hi after driving a Audi RS4 to BMW big difference Audi not problem BMW huge problem on these lights. 6 months driving then sticking back to Audi

@bozagacli 3 года назад

I have 2008 mini cooper with the same problem. It is not easy to reach place. I am planning to take the lens out. God help me!!

@Marksreviewsandtutorials 3 года назад

So the mini has the same problem? Such bad supply to BMW. Good luck with your repair. I had replaced 3 globes to this point, once I did this repair I never replaced another bulb.

@FearOfGeorge 8 месяцев назад

You could fix that with liquid tape

I doubt the insulation degradation is caused by heat. It's more likely caused by ozone created by the xenon bulb. Either way, the wire insulation is terrible and a recall should be issued because of these wires.

@Marksreviewsandtutorials 4 года назад

This car has normal tungsten filament globes. Not Xenon

@HomeWalkVirtualTours 4 года назад

Yes I was going to say the same, it’s not ozone as my dads 1992 850i has exactly the same issue and he doesn’t have xenons hence me finding this video

@y.u.doodat9133 4 года назад

Thanks, very helpful information! I have a 2006 330 CI convertible with the exact same problem. It's my second E46 BMW convertible, but it's certain to be my last BMW. As their slogan boasts, they may be considered by some to be "the ultimate driving machine". They do drive wonderfully when everything is working as it should. However, they're a royal pain in the butt to work on and repair. 😓 I'm going to have to try the same thing that you have done. But I'm not looking forward to getting into those cramped spaces with my big hands! (Anyone want to buy an "ultimate driving machine" convertible just in time for summer fun?) 😛
