Re-wiring existing roof lights

Hi all,

This is my first post in the forum as my partner and I just purchased a 2006 GMC E350 shuttle bus for our conversion!

I have done a lot of research and the electrical system for me seems to be the hardest part to grasp. It also makes it a bit difficult to think of adding lights to the ceiling when it's just got a whole one piece fiberglass roof rather than individual metals panels that school buses seem to have (same for the walls).

Ideally, I would keep the current wiring and just replace the light itself with power-efficient LED's

I was wondering if it's possible to do this and just make it so they run off the house batteries instead of the car battery?

Any help would be greatly appreciated - It seems to be a lot harder to find info for these fiberglass shuttle buses than skoolies

Sure ! it's easy. You want to take a bulb out and look at the tiny numbers or post a pic.

Decide if you want bluish light or yellower light. That's what they mean by temperature

Thanks for your response

is it possible to make it so these lights are powered by the deep cycle batteries we put in rather than the car battery that they currently use?

Sure ! remove the current battery and replace with deep cycle battery.


You are going to eventually want to get a DC power distribution system. Something that has some switches, gauges and most importantly- circuit breakers to protect wiring.

something LIKE this- do research, just grabbed this one, but it has a built-in charger for that house battery.

It's all here- start reading before you start spending!!!

Boat dc panel will get you by, but fewer features.

I would think that for temporary use you could find the fuse that powers the cabin lights you wish to repower remove the fuse and supply power from your house battery to the non power side of the fuse panel circuit BE SURE to fuse the circuit. Temporary only until you get your conversion going and install proper distribution center

Professional what? Electricians aren't real fond of these oddball 12V projects. You need to learn at some point...to maintain? It will get real $$$ to farm everything out. We can help.
