I used 12 volt cold cathode lights, the ones that go in your computer case, they worked nicely

How do you want them hooked up?
Like to a switch, when you turn your lights on, when you open your doors, etc.

Ive recently done exactly this and i have no experience in this stuff what so ever.

i used: cable strippers, 12v tester, a switch, gaffer tape, cable ties, 3x LED car interior sets, appropriate power cabling. (i had excess from one set of lights so im not sure what it is

i presume you will havemost of this stuff if you do audio installs.

the lights themselves were made to be plugged into your cig lighter. All i did was crack open the cig lighter (as one had a module inside for controlling them and resistors) and took the wiring to the cig plug on the inside, and connected it to the cabling. Firstly i put them where i wanted them, i used zip ties to hold them in place. I then secured all the cables back away from pedals ect. Next i took out my coin box thing that houses the cig lighter, just 4 screws to get into this. I stripped the + line that goes to the cig lighter at the back, (tested with the tester..) and wrapped up some power cord onto it, i taped it close to seal it, I ran this to my switch which  happened to fit neatly in a random hole in my car, ran some more cable away from this, Then all the + sides of the neon lights were "connected" to this. I stashed away the cig lighters from them in unseen areas so as to protect the inside resistors. (also lets me use the music function :P) I put 2 lights under the foot wells, 2 under the front seats, and 2 behind my sub in the boot. The front 2 sets were grounded via the cig lighter ground, its just the other cable back there that doesnt have a signal when the ignition is on while nothing is plugged in, i imagine it does when somehting is in it. Anyway the back set were grounded to the same place as my amp. It looks great, was real easy and was relitively cheap, took 3 $20 kits instead of a pro kit of 6 costing around $200. And yes i know i should have souldered them together, i will get round to it i just didnt have a solder iron nor did i know if it would work.

There are many ways to hook them up, do go with your doors, your head lights, etc, but personally i think this is the easiest, as your cig lighter should have a fuse. You need the ignition on for them to work, but i didnt mind that, rather be able to have em on when the doors are closed :P

sorry bout the uber long post, just got em done and had no one to share it with, good luck with your install!

He's right the cigarette lighter is a great place to tie into for something small like this. Just be sure that your total amperage won't exceed the fuse that is currently in there.

Sorry, you can NOT post a reply.
