If it's causing a voltage drop you wired it up wrong. I've run my rock lights (4), led lightbar, interior lights, headlights, and radio without the jeep being on. Never had an issue for the 20 minutes it was like that.
Hey...I have 4 rock light, 3 sets duallys led lights....1 light bar, winch, compressor etc. All hard wired to batt. They are wired correctly...certain items trigger a slight Enough drop in voltage to cause the (superchips) Traildash to turn on. You would think it would only turn on by starting the engine but other drops in voltage can do it as well . I can have all four LED's on as well as headlights and interior lights and the trail dash wont start but the watts/volts that were being pulled by the original rock lights were too much a drop. I think they were 60 watts each - 240total. Thus, trail dash would come on and Then get stuck in a holding mode BC engine not on. same thing happens if I use a compressor or the winch with the motor NOT on. Once I switched to the LED rock lights, I had no issues anymore because it was a negliguble drop in voltage when motor is not on. I called superchips about this and they said that that is how it works.
Either way I'm in the market to find some good LED replacement Rock lights as I don't like the Walmart platinum burner version
