I have an 09 bighorn crew cab, it's my first dodge. How can I tell which headlights I have? There is a separate bulb for the high and low beam, is this a quad?? Or I have seen it called a 2 or 4 light system...help!!!

 

Yeah those are the quad bulbs. Mine just has one bulb per headlight. Are you looking for a bulb number or what? If so, your low beams are H11's and your High beams are 9005's. Here's a link to get all kinds of bulb numbers for your vehicle.

I can tell from a long distance which ones they are. The Quads have the amber up the sides and part of the bottom. The basic ones just along the bottom. See my sig below compared to the sig just above.
