hi guys (and girls), i'm hooking up some neons inside my car to a switch. I was looking at the article on this site "how to wire an illuminated switch" and it made sense to me, but i'm wondering if and why i need to get some sort of fuse for my neon lights. some of the lights i'm hooking up come with a transformer, is there a fuse in there already do you think? i'm pretty stupid when it comes to fuses so could someone also please tell me how i'd go about wiring up a fuse??? thanks.
