All our Illuminated roof signs use LED's, which use much less power than traditional bulbs. Illuminated roof signs can be plugged in or out of the roof sign itself.
You may opt to use a cigar lighter plug or wire directly into the side lights of the vehicle, so when you turn on the lights the roof sign will illuminate, however prior professional advice is advised.
