Difference Between High And Low Beam Headlight Bulbs

However that s not true across the board.

Difference between high and low beam headlight bulbs.

One is for the low beams and one is for the high beams. Most modern vehicles have a single bulb with two filaments. They are sometimes referred to as main beam headlights. The second filament lights up when high beam is called.

The difference between low and high beams is that low beams are used for normal nighttime driving while high beams are used in rural areas or small roads with very little or no light at all. These terms are synonymous and the term used depends entirely on the region. Some cars mostly higher end vehicles or performance vehicles do have separate bulbs for their high and low beams. In the past high beams and low beams were separate bulbs on all cars.

But generally all the beacons are placed in a particular way that the area in front of them is visible and not much is seen because all the lights are in low beam light and only on high beam turn on the intensity increases and the distance covered is rapidly more. The low high beams are the same bulb. High beams are distinguished from low beams by their brighter light. If you take the bulb out you can see that there are two filaments.

Today that s not the case.
