Lightbars?

Stick with something that doesn't pull more then 4amps actual if on a seperate system, 2 if wired in with the other lights. LED light output wattage doesn't convert directly to amp load but use a watt-to-amp converter and cut the amp result in half and you will be pretty close. For example I have a 24" light bar on my Z that should have pulled about 9 amps but in reality it pulls 4.6. I can verify with my Amprobe that reads DC and AC amp loads. I also have another 7" on back that should have pulled about 5 but only pulls 2.5.

Thanks for the info. That helps alot.
