I am ready to make my car really shine, adding under cars neon and 4 tubes of 6in and 4 tubes of 9 in red neon to car. Have added a Optima red top battery for this reason, so ready on that side anyone have any advise for me on this. I have installed some neon before on system but never to this extent I am very excited about this.

You can do pretty much anything you want. One thing to consider is if you want all the lights to come on at once or if you want differant circuits. The hardest part of the LEDs in my car is deciding what functions I want and how to do it. I am still undecided to this day and theyve been in for over a year. Try to hide the wires the best you can, and DONT use the cigarette lighter adaptors, they look so tacky.
