I used a roll of SMT RGB led's (the one's you can cut down to 4" strips) and there are 3 led's per 4" strip. I wired the blues up in the footwell. I was worried about light disbursement at first because of the dome lights. But, the end result, w/ the dome lights so dim it actually has a nice mellow look to it. The dome lights act more like mood lights and the foot well lights leave a nice blue hue in the lower section of the cab. It could make a nice *******' wagon.
