YES!! Been thinking the same thing with my DT300i and since my ride used to be a Yager, it should apply. There are two relays, one high beam, one low beam. Find the one for low beam since that is the one that comes on with the ignition. Identify the two pins that are attached to the coil in the relay, pull one of them (preferably the one that goes to ground) and wire a SPST switch between the pulled wire and the blade on the relay. You can mount the switch anywhere you want depending on switch size. I am going to try mounting mine in the right grip housing. You may have to rethink this bright idea if there is a plug shell into the relay.
