Left my light pods on overnight.

I haven’t. What do I look for?

 

Bad ground, pinched wire, faulty relay? Anything that looks like it got too hot, discolored insulation on the wiring. If you have any cordless tools, like 18V stuff, you can try hooking the light up to the battery with two jumper wires (unhook the light from the wiring on the truck first). If it works, you’ve got wiring issues on the truck probably.

 

could I use the trickle charger that’s connected to the wall?

 

I’ve never tied that, not sure.

 

Maybe not the LED itself but a number of components can burn up causing low emittance. See it all the time on headlights with drop in LED's.

 

ok I plugged them into my other LED lights wiring and they are still bad. The lights are bad I guess.

 

Not quite right. "White" LEDs are a blue LED chip with a phosphor layer sandwiched over the die. The phosphor layer glows when energized with blue/UV wavelength light, emitting some red and green wavelengths of light, which all mix and produce some resulting shade of white light. Typically an overheated LED begin to burn away the phosphor layer, resulting in more and more blue light escaping conversion, resulting in *higher* color temperature light, then the die itself will burn out. Depending on how hot the LED is getting, this may happen nearly instantaneously or slowly over a period of hours of use (think, poorly heatsinked retrofit bulb).

Typically a white LED will not get warmer/yellower when overheated.

LEDs can experience some "tint shift" depending on how hard they are driven, but I don't think a typical high power white LED is going to shift dramatically from 5000ish k white to yellow.

 

"I don't think a typical high power white LED is going to shit dramatically"

And that's a good thing!

 

Lol, forgot an "f" there.

 

That would have explained the color change though.

 

Well no, again, I meant tint shift to a warmer color temp/yellow in appearance. Tint shifting to blue, I can see if they were overheated slightly for an extended period of time. I would almost think its some issue with the lens, if the lens is polycarbonate it could be hazing over from overheating, but even that seems unlikely.

I'd be really interested in a locked camera setting shot of the beam, and an up close/in focus of the LED through the lens with the light turned off to take a look at the LED, if the OP could provide those pics for reference. This is a really strange failure mode for an LED based lam0.

 

Wow they are honoring my warranty and even sending me replacements all the way here to the Middle East. I love KC. Definitely will continue purchasing their products. They want me to destroy my old lights which seems fair.

 

KC is a good company. I've used their lights for years, including my current truck.
