Hi all
My rear 3rd brake light has stopped working. The only related thing that happened was when I opened the boot in my garage it hit the inside of the raised garage door, would this stop it working, theres no marks on the red lense or anything. I understand there is no fuse for these. Could the slight bump make it stop working? I have no warning lights. I did google and removed the negative battery terminal for 30 seconds but didnt solve the issue.
Are there any other reasons the 3rd lamp sttops working? Any ideas please?
I have removed the lamp and ordered a replacement although they are not cheap for a used one just in case I need one.

 

A search of this site shows many have experienced “finished or burnt” LEDs.

I would start with a check to ensure the connector is in fact firmly connected as you mentioned there was a mild bump…

 

Hey @markva44. While nothing like an incandescent bulb, LED's can be damaged if jarred hard enough. There isn't much to them. Connector in, connector out to ground.

 

I had a diode blow in my CHMSL, I found the PCB, replaced that one diode, and it still works now nearly ten years later.
Of course I don't know if a jarring would cause that, but who knows...

 

Thanks for the reply, I removed the 3rd light and connector was fine, I did notice some moisture behind the red plastic about half the internal length
