Got all my M35A2 LED lights working....for a little bit. Anyone worked on LED's with success?

After spending the time to refresh all my grounds and confirm all connections, I discovered that the most trouble prone LED lamp on my truck has a cracked housing, letting who knows what into the case, leaving it free to attack the board.

My left rear LED lamp hasn't been giving me any trouble, but I found a reasonable deal on two new replacement rear lamps and will fix the rears that way.
The fronts work...good enough...for now.

Thanks to all who took the time to read and respond!

My new LED rear lamps arrived today, and it was a quick job to swap them out. Since only one of my old lamps was bad, I now have a spare rear lamp.

I was surprised to see that the new Trucklite LED rear lamps only use 3 LED's for the tail/running light. The Grote's I replaced used 12 for tail, and 12 for brakes.



I haven't had an opportunity to check them in the dark, but I believe I've solved my issues for now.

Many thanks to all who read and replied.

Found this on my 1061. Both sides had one wire between the light housing and mount that was smashed enough the wire came through the insulation.

Then I checked and the ground for the bulbs in the top is one screw and the ground for the lower led is the other screw.....and they are not bonded inside. Thus you can have a fine ground to one of the housing mount screws and the light still not work because the other mount screw is not a good ground.

Moral is to check both of your mounting screws to make sure both are making good ground, not just one.

Thanks Toby! I found two new LED lamps for the rear of my truck...and all is well!!
