Smart-Radio Interface for Adding a Full-Range AmplifierWant to add an aftermarket full range amplifier to your factory audio system? Some modern radios require a consistent level of resistance (called a "load") to keep playing through the entire trip. Without that load, the stereo system can shut off unexpectedly. The KISLOAD4 Smart Radio Interface prevents sudden shut offs by making sure the resistance stays consistent. You get great, consistent sound for the entire ride. A great little piece to add to

Nice headlight. Minor wiring flaw.
Great looking lights. They come wired incorrectly. You will have to changes the pins around so the high beam and low beams come on when the switch is in the correct position. Or you can just have high beams on when the low is select and vice versa.

They look good but don't work properly
The headlights are bright no doubts about that. The fitment is not the greatest fits ok on one side but not the other side so good now for the most important part. The functionality is sketchy i spent hours trying to get the blinkers functioning correctly without any luck. Pretty cool looking but they have not worked out all the kinks
