I'm looking to replace my headlights but I'm a bit confused. The OPT7 LED headlight kit caught my eye. However, I want to know if a) the hi/low beams are 2 separate bulbs (meaning there's 2 headlight bulbs on each headlight assembly, not including the turn signal bulb), and b) does the low beam bulb also serve as a DRL and would the OPT7 bulbs be able to function as a DRL as well as a lo-beam light. If anyone purchased this assembly before, I'd love to know how'd it go! I've been a bit sketched out about purchasing headlight bulbs since I work at a warehouse and we get a lot of returns for headlight bulbs so I have this notion that aftermarket bulbs will fail on me one day while I'm driving at night..
