Buick Regal Dual Beam Headlight
About dual beam headlight
A dual beam headlight as the name suggests, projects "dual beams" from the same headlight bulb, which means, it emits both high beam and low beam. It is a especially designed bulb that allows the two beams to be produced through the same bulb which reduces the number of bulbs required from four to two since a single bulb produces both of the beam patterns.
What is the purpose of dual beam headlight?
A double beam headlight has the purpose of producing both the beam patterns using the same bulb. This reduces the number of bulbs used for the same purpose, also allowing more compact and sleeker headlight housings to be designed adding to the vehicle's aesthetic value.
How dual beam headlight Works?
The headlights with dual beams are basically dual filament bulbs. The same bulb has two filaments, one towards the lower end and one towards the center of the bulb. Two separate circuits are integrated into the same bulb, and the individual circuit is completed based on the driver's selected beam mode. It saves both time and resources because only one bulb on each side needs to be replaced for both the beams.
Where is dual beam headlight Located?
The double beam headlights are present on either side of the vehicle's front in headlight housings. They sit on both sides of the barbecue. The exact location is however subjective to the manufacturer of the vehicle.
