What lights exactly? Dome lights? Map Lights? I don't know of any lights in the doors besides the switches...
Theres a little light in each door that come on when the door is opened...I'll put up a pic. These. Pretty sure every truck has them. I probably just didn't describe it well enough.
oooh ok. I have no idea... the best bet would be to take the bulb out and look for any numbers or letters on it
