just connect a wire from the DRL + wire to the sidemarker + wire and voila! your halos are automatically on during the day and at night like mine!
i have the BFXenon RS HID Kit, and i originally had the AAC LED DRL bulbs with their "wiring harness" to keep the halos on during the day and DRLs on at night. that "wiring harness" consisted of 2x 8" long wires and 4 T-taps to connect the wires like i just stated above. since the HID lights do not draw power from the stock DRL wires, i felt it was safe to leave the "halo wiring harness" in place so they stayed on automatically during the day.
