Okay, I just finished installing the lights with the Skene dimmer, and I get no light.
Following the Skene directions, as they were the only ones in the box, I wired the two black ground wires coming from the light harness to the two blue wires coming from the Skene box.
The two black wires from the Skene box were attached to the black ground wire from the switch, and then to the negative battery cable provided with the lights. The red Skene wire was connected to the red switch wire, as I wanted the switch to control the 12v+. The white Skene tapped into the high beam wire coming from the high/low switch on the bike.
I left the yellow unconnected, as I don't care about adjusting the low output on the fly.
So...what did I do wrong? I am certainly misunderstanding something here.
