Side marker lights that blink 

One of the simplest and best explanations anywhere on the internet

Thank You for the video and the information. Could you please provide a part number for the 5-prong relay?

Thank you so much brother

Only problem with that is that the markers don’t blink at the same time as the indicators

when i attempted I noticed that my flashers/turn signals ONLY work while my side markers/ Park lamps are on I don't have auto or DRL feature on my 01ram I don't want to have to turn on my Park lamps every time I change lanes .so my question would be if it would be an issue if I ran a second wire directly to LED signal light? thanks

So where is the other relays for the other side?

Am looking to add turn signals to my side mirrors. Do you need a relay for that? I just need to tap into my signal wires but am clueless.

Would one relay handle both directions or would I need one relay for each side?

I have a 1985 nissan 720 and ive tried this and it does not work no matter what i try the markers will come on but will not blink. What am i doing wrong? Do i have to change the bulb? Does it have to be an LED? Can you make any bulb blink? Im lost please help

I did this but when I use my turn signals the parking lights don’t work after

Where would you put it if you had to do it on a car dolly trailer?
