What Are Side Marker and Clearance Lights?
LED side marker and clearance lights are installed on semi-trucks and trailers to increase the vehicle’s visibility. Side marker and clearance lights differ in how and where they’re used. Side marker lights are installed on the front and rear side reflectors to make the commercial truck and trailer noticeable to other drivers. Clearance lights are installed along the upper edges of a truck or trailer to denote its width and height.
Can These Lights Be Used As Turn Signals?
Certain lights can be used as both a side marker light and a turn signal. These ‘Mid-Ship Turn Lights’ can function as mid-turn signal lights, side reflectors, and side marker lights. These lights feature an oval shape and emit an amber color.
