Post pro comp lights?
I am installing 2 pro comp 55 watt lights this weekend does any one know how long these lights should run on my starting battery while running at slower speeds when the motor isnt charging the battery?

2 55 watt halogen lights= 110 watts
volts x amps = watts
12 x 9.16 = 110 watts

lights will draw roughly 10 amps

i had 2 55 watt lights and upgraded to 2 -27 watt led lights(1 spot,1 flood beam) amps went from 10 to 4. Longer runtimes plus they are 3 to 4 times brighter.

I set up 2 of their 8" 130watt lights last season (wired in parrallel). We tried to calculate the number of hours it would take to drain the battery and never could settle on a solid number.
They would run for 2 hours without any problem, I just never had a need to run them longer. It seems like they will run a good while longer.
