so i got my synergy lights in today and im having some difficulties installing them. last time i bought some, from what i remember, there was only the 2 prong plug from truck to balast and 2 single prong from bulb. with this, i have an additional 2 prong plug that plugs into the red 2 prong plug from balast with 2 bare prongs that i figured out go into plug from truck itself. is it safe to leave it uncovered like that, or am i missing something?
