Buick Regal Low Beam Headlight

Low Beam Headlights are the part of the front headlight assembly and are switched on when the headlight switch is set on by default. Such lights, also known as dipped lights, have a limited visibility range as they are oriented forward and downward in direction. In such conditions, they illuminate the path ahead better and therefore do not blind the oncoming drivers which could otherwise cause accidents. Such lights are useful in high-traffic conditions and also to prevent blinding the drivers on the opposite side when the cars are moving faster that usual.

Due to extremely dark conditions or even rain, when the driver's visibility drops below 150 metres, the low beam headlights allow the driver to have a clearer view of the previously blinded area. It also increases protection by keeping the beam centered during bad weather conditions.

By default the low beam headlights are activated when the headlight switch is switched on. The low beam headlight relay is powered by activating the low beam lights when the headlight switch is put on through the turn indicator stalk or the stand alone switch. Because of the resistance, as the current flows through the filament inside the bulb, the filaments heat up and thus glow. With the help of mirrors and reflectors this light was produced in focused and evenly spread.

The low beam headlights are mounted in the headlight housing at either side of the front of the vehicle.
