Problem: Incandescent bulbs burn out and LEDs create obnoxious unnatural light...
So I started out with a regular courtesy lamp kit. Since I off road quite often the incandescent filament would blow out all the time.
I replaced the bulbs with a LED equivalent from a car parts store. The result was that the light was an unnatural bright white light and cast a focused beam on the ground. Not the best solution for a courtesy light.
Then I replaced the bulbs with a flea-bay upgraded set that had 9 LEDs per bulb, that were warm white color. Same thing, focused beam, intense to look at and they would flicker off and on all the time.
So I went down the rabbit hole of LED lights, tinted paint and light diffusion. Here are the results, evenly distributed soft natural light with a bulb that is epoxy sealed, good for as long as I could hope for and easily found-replaced.
