Can anybody tell me if xA or xB headlight bulb assy are separate for high/low, or are the bulbs on the same assy?

I'm looking to get HID's, but I'm a lazy ___ to check my headlights. Actually, I'm so busy, that by the time I get to the car, I always forget to check, and it's gotten to the point where I need to buy them today, but I don't have time to leave work, walk to the $@# parking garage, and check the bulbs.

Ex. High/Low beam bulb (2 bulbes in the housing)


Ex. Low only bulb (1 bulb in the housing)

 

Go get your owners manual. It is your friend. It holds the answers to many questions.
Or you could do a search.

 

one bulb, two beams

 

It uses a single H4 bulb per head light, conventional H4's are dual filament.
