What's the difference between Dual Beam and Single Beam headlight bulbs?
“Do I have dual-beam or single-beam headlight bulbs?” The answer to the issue often brings confusion, but it is surprisingly simple:
The term “Dual” and “Single” refer the function of a headlight bulb. A dual-beam headlight bulb has dual functions; The bulb creates a low along with a high beam – “dual beams” in a single headlight bulb. A single-beam headlight bulb has a single function; the main one bulb creates only one beam (either low or high beam individually).

HOW To recognize SINGLE BEAM BULBS:
Just remember if you’re taking a look at an LED headlight bulb or HID conversion kit and you’re unclear about the difference, just remember to focus on the bulbs themselves, not the headlight housing. Have you got a bulb that does 2 beams in 1 bulb or 1 beam in 1 bulb?
