When using these lights with the DRL, the Idea is to run the DRL s during the daytime and allow the main auxiliary light to come on automatically with the high beams. DRL s automatically come on with the key.

The standard wire harness will allow the DRL rings to be on when the key is activated and the main auxiliary light to come on when the high beam is activated.  No switch required.

However if you are wanting a low and high beam function you can do that by adding the Skene dimmer and a cutout switch. The switch would allow you to run the DRL s only during the daytime, but at night activated the main auxiliary lights with a low beam that is adjustable from off to 100% in 10% increments. The lights will automatically go to the preset low beam setting via the bikes factory headlight switch and go to 100% in high beam. the added switch simply disables the main auxiliary light, not the DRL rings.

The Skene IQ-275 is for bikes with conventional halogen headlights

The Skene IQ-275 X is for bikes with factory LED headlights. This does not include the BMW line which does not have access to the high beam power wire. Those bikes require the hexcan. Hex Ez Can gen 2-HEX (cyclopsadventuresports.com)
