Marker Light

Marker lights are illumination devices attached to the front, both sides and rear sides of motorized vehicles and trailers. Marker lights should reflect orange at the front and side, red is used at the rear side. These side marker lights help other passing drivers to know the length of the truck at night in places where there are no street lights. They function as auxiliary safety lights that can be seen by other drivers when the vehicle operator turns on the headlights. They are standard equipment on most vehicles and can also be purchased and installed as aftermarket options. Side marker lights provide extra illumination at night and during times of poor visibility to help other drivers and pedestrians see the vehicle. Side marker lights are standard equipment on buses, trailers, cars, trucks and some work and utility vehicles. Side markers usually consist of one, single-element bulb, either a carbon filament bulb or LED (light-emitting diode), which is encased in a socket and small frame. The frame attaches directly to the vehicle's front fender and rear quarter panel with screws or snaps retainers. the lens of a side marker, made of high impact, translucent plastic, is amber-colored for the front of the vehicle and red for the rear. Side marker lights have single wires, which lead from the bulb socket to the parking light wire, taillight or main headlight wire loom. They use the standard automotive 12 volts for operation and activate when the headlights are turned on. These lights do not need any extra switch to make them work, they just glow when parking lights or the headlamp is switched on. Marker lights come in different shapes and sizes. These lights are easy to repair and replace.
