The high-beam indicator symbol in a vehicle depicts a headlight lamp with a series of horizontal lines to the left of the lamp. There are usually four or five horizontal lines. The high-beam indicator is usually blue, but may also be white.
High-beam lamps are usually activated by pushing or pulling the headlight or windshield wiper control lever that is normally found on the steering column. Some vehicles, however, have buttons that control the high beam lights.
High-beam lights are intended to temporarily illuminate very dark roadways and can help drivers avoid debris, animals and other obstacles on and around the road. High-beam lights should only be used when there is no oncoming, parallel or intersecting traffic.
