Im putting in 3 neon tubes(OPTX ULTRA MINI NEON 3 inch) in my car to add a little lighting to it.Heres my question i want to put the lights to a toggle switch and i need to know do i wire these lights in series or parrall(sp) Each light has its own transformer.

Any help would be great
Thanks

 

I would go with parallel, like each light gets wired back to the swtich and each light has it's own ground. Then the other side of the switch has one power wire/supply with an inline fuse. Get your power from the interior lights, that way it will get it's power from the acc fuse.
