What do low beams do?

Low beam – Low beam headlights deliver light in a small area (about 200′) while limiting the light directed at the other drivers’ eyes. The short-range light emitted from low beams is ideal for driving in traffic when you don’t want to blind other drivers with your bright high beams.

How do high and low beams work?

The difference between the low beam headlights and the high beam headlights is the distribution of the light. When the low beams are on, the light is positioned forward and down so as to light the roadway but not affect the drivers who are driving in the opposite direction.

Most modern vehicles have a single bulb with two filaments. Some cars (mostly higher-end vehicles or performance vehicles) do have separate bulbs for their high and low beams.

Why does my high beam work but not low beam?

High beam headlights don’t work or low beams don’t work. The cause: A burned out bulb, or a problem with the high beam switch or relay. The fix: Replace the bulb, switch, or relay. If just one bulb fails to work in either high beam mode or low beam mode, it may be the bulb.
