For all the guys running 40" plus light bars, do you have to upgrade your battery or electrical system? I imagine it's fine while driving but will it handle the load at idle?

  • Plus rear lights, plus 900 watt stereo! On normal battery.... yes I should

    Probably run dual set up, but to many miles on my rig to set up.... will wait till

    I upgrade. But as long as I run anything while I'm driving there hasn't been a problem

  • I didn't mines a 50 inch

  • Good to hear. My Ranger gave me fits with a stereo and 150 watt halogens which is a different ballgame but makes me nervous to start down that path again.

  • A 50-inch light bar only pulls about 4 1/2 amps.

  • Running a 52 w/o problems.

  • I had a winch, stereo, and light bar. burnt my stock battery up within a couple months. bought a optima yellow top and haven't had a single problem

  • Good deal, sounds like the light bar is going on, thanks!

  • New leds don't pull much power you should be just fine

  • Mine had a 50 inch, and as long as I was running down the road about 30 miles an hour, it was fine. In the woods I could watch on my digital voltmeter and the battery voltage with drop below 11 volts. Stock battery

  • I have a light bar a winch and a sound system and mine holds up fine
