3RD brake light issue
1 Attachment(s)
Hi all, happy Friday.
I purchased an LED 3rd brake light from Robznob11 and installed it. WORKS GREAT WHEN STOPPING! only if the driver or passenger door is open. ??? wired it into the brake light switch white wire. 1970 c10 2wd. any suggestions? |

Re: 3RD brake light issue
If I read this right, for some reason its using the same ground as the courtesy lights. If so, when the doors are closed, there is no ground for the light - that is why. You have to ground the light separate from the courtesy light circuit.

Did you replace the brake pedal switch to a 3 wire? You need a dedicated circuit going to the 3rd brake light.

I just installed mine a few weeks ago and I also had to change the ground wire to the back of the screws holding it in place.

FINALLY got around to changing the ground. I did what Andy4639 suggested and now i don't have to open the door when stopping to make the third brake light work. Thank you for your help fellas as usual. |
