    I'm looking for the correct headlight harness for my 1993 Suburban, and fishers eMatch on their website asks whether the lighting system is 2B or HB-3 / HB-4. I don't know what this means.

    This is the headlight setup I have (not my rig....just found a pic online and posted it here).

    I'm going to say you have HB 3-4.

    Mark is correct. The Sub in your pic has the HB3-HB4 lights.

    Composite is the giveaway. 2B's are sealed beams.

    thanks guys, I assumed that was the correct answer; I technically have 4 bulbs, and the work truck style has 2 bulbs, so I assumed that 2B meant the work truck, sealed beam style, and the HB3/HB4 was what I had.

    BUT...you know what happens when you assume.....
