Ok i have a total of 5 in my car two under the dash (one on each side) they are 8" and powered by splicing into the stock wires for the under dash bulbs, and I have 2 more 8" in the back one behind each head rest (powered the same way) I just ran my wires along the door like all the stock wires. In my trunk I have 1 18" neon that is hooked to the under side of the trunk in the same place that the stock light is and its powered via being spliced into the stock wires for the trunk light. None of them are visable ynless you get low and look for them.
All my lights are blue, headlights corener lights, side markers, neons, license plate lights, reverse lights,(well some are hyper white)and the dome lightis a black light. So now my car has the blue light look to it FWIW.
