excellent
Color: 1PC Amber White 6 Modes Lights + Wiring, Size: 12Inch Light Bar
The light is impressive with six modes. The wiring harness was already prewired relay and a protective cover over the wiring. One problem was the sizeable in-line connector for the switch made it difficult to place it inside the vehicle due to the length of the wire. Negative--The mode switch will not work unless the power is on and no indication of which mode it is currently in.
