I bought a 2005 F250 CC w/ a short bed. Already had the cap on it (I want to take it off and get a Bakflip once I get some money). It is wired for the brake light and interior bed light, but the fuse was blown and the bulb had a hole in it when I got it.

So I'm looking for the information (volts, watts) for the lightbulb that sits on the inside of the cap right behind/below the exterior brake light.

Anyone know what kind of bulb that is?

 

Look for a website of the cap manufacturer. I'm sure that there is not a universal answer for your question.

 

My leer caps light was out also.. Used the calibrated eye ball and picked one up at auto zone... Was actually a dome light bulb...

 

That was my plan, but in the process of looking for a new bulb I crushed mine at some point. I think it was 3V 9W, but I'd like to see if someone could chime in.

LEER just calls it a dome light. I guess I can probably just call them.

 

did you ever get this figured out?

 

No, never got around to calling.

 

Just looked at the one in the truck cap and it's the same style that is used in the cab mount lights on the truck.
