Wheel house tail lights

[harvey lee]

Both were working fine one month ago.

I noticed the other day, the left side of the house tail lights are dead. No tail light, blinker or brake light and the other side works fine. Used a test light and checked the wires and they work right before the light assembly. I took the 2057 bulb out, the wires look fine inside the bulb.

Now I took my test light and grounded it on the light assembly where it screws to the fram, then I put my headlights on and stuck the end of the tester into the socket and it's hot, did that with the blinker also and that blinked.

Is my light assembly shot or what am I missing? I have juice for all to the light bulb socket but when the bulb is in, nothing. Yes, I also tried a new 2057 bulb with nothing.

I pulled the little black piece out from the socket and then put the bulb base against the socket piece that is hot and nothing again.

So I have power to the socket but no bulb lighting up, new one for me. I typically can fix tail lights but this one I am missing something for sure.

Put the bulb back in with the test light connected to the same spot as before and touch the ground on the socket. My guess is the test light will light up. If it does the ground is open. Bad socket, bad light assembly.

Make sure where it mounts to the frame that it has a good clean tight ground. Test the ground with an ohm meter by touching the socket with one lead and the frame with the other. You should have 0 resistance. The ground could be corroded off inside the assembly or simply not grounding to the frame. When it does your lights will work!

I had hecked and cleaned the ground wire so I thought I was ok there.

Exactly what happened Jer, I ordered a new set of LED tail light assembly's, no sense of replacing one and may as well get 2 new LED assembly's.

I thought maybe it was a ground issue and a bad assembly but I was only guessing, not a wiring expert.

Last year I replaced my boat trailer light assembly's and my alum utility trailer got the same treatment with new led assembly's.

Thanks' for the help guys, figured it could get resolved right here as usual.
