ive got some neons that i want to put in my car but my 12volt is broken, i have bought a new one but i dont know what wires to connect, and is there a way to just wire the lights straight into the 12v, thanks

Huh???... if the neon is for a 12v sorce then yes all wires in car are 12v sorce and you can wire them right in, then just ground it.

Just hook it up to your battery or any power source in your car and make sure you put a fuse on it.

personally, i wired my interior neons to the dimmer light wire on my radio wiring harness.. and used that ground too... works great for 2 neons.. and i can dim them with my dash !
