The all new 12 foot interior Strip LED light Kit utilizes SMC Hi-output wide dispersion flat LEDs to give more light and maximum flexability for installation. 3M brand two way adhesive allows the strip to be mounted almost anywhere. 210 LEDs, uses 27 watts, 2.0 amps and puts out 875 lumens per strip. Work on any 12 volt charging system, with or without a battery. Strips can be cut with a sissor to desired length. If you want a switch, any standard low voltage (the cheap ones) will work fine. Just pick out the type you like (ie rocker, button, flip, etc. switch). Kit includes one 12' strip, mounting tape, and instructions.
