LED light bulbs not working when installed in slideout

But is there LIGHT when you flip the switch and say LET THERE BE LIGHT?

(Makes you feel godlike when it happens don't you know :) )

My suggestion would be to find the 12V feed to the light circuit going into the slide and just reverse the - and + and that should solve the issue. On one rig we had, I had to do that because it was reversed in polarity in the slideout and the item I was installing would not function as wired.
On my present coach, some of the bedroom ceiling lights are of incorrect polarity and some LEDs will not work correctly.
Hope this may help. Happy trails bert

Thank you all! Most appreciated!

My daughter's popup lights were reversed and she could not get the leds that I gave there working. I explained it to her and she is super happy with her new fixtures.

Same here. with old incandescent lamps polarity don't matter
But with LED's Well some are wired to self correct for polarity errors (my favorite 20 buck a pop lamps do that) some (my favorate less than half that) do not and the techs who wire the fixtures for 1141's well. they don't always pay attention .. not to mention some lamps can be reversed as well.

I have some marker lights where it does not matter how you wire the socket but the wedge based lamp only goes in one way the other way it don't light.

That would be my guess.

Try installing them using a mirror. Might fool them.

There are flat panel leds that allow you to change polarity by flipping the plug.

Thanks for the tip, I'll check into that!

Sounds like reversed polarity in the slide out wiring.
LEDs must be wired with the correct polarity or they will not work.
