Courtesy light bulb and dome light questions

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
