They work [censored] decent. I have a couple friends that race off road and they switched to rigid LED light bars and they really do a nice job.
They run One LARGE light bar above the roof line, with two smaller lights aimed slightly off center, a smaller square lamp on the A pillars and a 10 inch bar behind the front guard.
the only thing that i dont like about them is the price. But they do put out a great light pattern
