Courtesy light bulb and dome light questions
 

I have an 84 GMC Sierra 2500, that didn't come with a dome light, only an under dash courtesy light, ( or cigarette lighter,) but was wondering if someone could tell me what bulb number would go in the under dash courtesy light? I have power so it should work. Also, if anyone else here has a truck without a dome light, what did you put in to light up the cab? I was thinking of an RV style porch light or something similar. Can you post pics, please?
Thanks

I added a set of courtesy lights from LMC and used these led bulbs. It adds a lot more light, sense you don’t have a dome light. Now if the new bulb doesn’t work, then your door switch wire has rusted and fallen off the back of the switches.
The bulb size is 1003 or get the led equivalent

Thanks for the tip. I checked the socket with a test light and it comes on, so thinking maybe my bulb is bad. I just found one to put in and test the socket.
Those LED's definitely light things up, don't they?

I switched mine to the 1156 style led...its more than twice as bright as before...but these trucks were never had greatly illuminated interiors

I found a simple done light solution. Got a magnetic mount LED light that's dimmable and mounted it in the center of the roof.
