A dual-beam headlight system uses one bulb for low and high beams. The bulb creates a low and a high beam – “dual beams” in one headlight bulb.
High-beam headlights shine at an angle to illuminate the road 350 to 400 feet ahead or about twice as far as low beams. (Remember that 68 mph equals about 100 feet per second. When you travel at highway speeds at night, low beams may give you only a second or two to react to a hazard.)
Dual beam headlights are a type of automotive headlight that uses one bulb to produce both low and high beam lights. The low beam is designed for wider dispersion for city driving and driving in low visibility circumstances.
The high beam is designed for far-reaching visibility when driving in rural areas and at night. Dual beam lights use the same bulb for both beams, providing a more efficient use of energy and a more cost effective solution for vehicle lighting.
