5 3/4" Daymaker questions
 

I just bought a Daymaker LED headlamp for the wife's 2014 Sportster. Upon installation, I noticed a standard 3 prong headlamp socket on the rear of the light, along with a single loose red wire. I plugged in the headlamp, but have no high beam. There is no mention of the loose red wire in the instructions, is the light defective, or is the red lead supposed to go somewhere? Thanks for your time.
