Low Beam Headlight
Low beam headlamps are used as your primary source of light while driving and is intended for use whenever other vehicles are present ahead. Low beams provide a distribution of light designed to provide adequate forward and lateral illumination with limits on light directed towards the eyes of other road users, to control glare. More
High Beam Headlight
High beam headlamps, often referred to as “brights” are used as your secondary source of light while driving and only suitable for use when alone on the road. High Beams provide a distribution of light with no particular control of light directed towards other road users' eyes as the glare they produce will dazzle other drivers. More
Fog Light
Fog lamps provide a wide, bar-shaped beam of light with a sharp cutoff at the top, and are generally aimed and mounted low. They are intended for use at low speed to increase the illumination directed towards the road surface and verges in conditions of poor visibility due to rain, fog, dust, or snow. More
