So I replaced all my lights with LEDs (except the glove box biotch), and all have worked well EXCEPT the left side license plate bulb.

The first time it dimmed, I thought it was a bad bulb, so I replaced it. This time, it dimmed again in a very short period of time, so now it's a pattern.

Have any of you experienced this problem? Could it be from washing the car and spraying that area? Or maybe I should just leave the regular light in there, even though it's yellowish? Please advise.

 

I doubt it's from washing...otherwise everyone would experience it.

Maybe the wiring has a bad connection, that would explain why it isn't always like that. It might be a loose connection

Or the bulb might not be in the correct way/enough. try to check those two and if it's still happening then I

 

probably just a coincidence. Not a pattern.

 

Your ground wire connection is loose or corroded to that light. Bad grounds produce dim or inop lights. GL

 

ty, that makes sense, but why does it start off working perfectly for a few weeks, then go dim all of a sudden? twice? shouldnt the 2nd time i replaced it have gone dim from the get-go?

idk...

 

ill check the connection tomorrow. as far as the wash, i use the coin self-wash spray, which is super powerful, and shoot into the license plate area. but now that i think about it, if the water got to it, it probably would go out and not dim.
