I sell lights and sirens we also make hi power leds for law enforcement. The newest white LEDS today 6-29-2010 have very impressive light output, Its all about having correct optics or proper precription. You could get a LED light made by Whelen engineering that would draw 1/2 amp each. Compared to your 110watt lights @ 12.5VDC= 8.8amps per lamp or LEDs with a 5+ year warranty that draw 1 amp total for a pair. Its going to continue to get better lights optics etc home business automotive the market will grow.
