I just finished mounting a couple of 50W LED running lights to my daughter's '98 883 Hugger. I used a couple of old Dyna turn signals that I gutted and added the LEDs to. They are wired into the aux lighting in the headlight bucket and come on as soon as you turn on the key. Since they are LED, the power draw is minimal.
