Unlike a turn signal or brake light, a marker light stays constantly illuminated whenever the headlights are on, giving surrounding traffic a fixed reference point for judging the outline of a truck, trailer, or wide load rather than a moving signal to react to. This is why marker lights are non-negotiable equipment on commercial vehicles and heavy trailers in particular, since a vehicle wider than a standard car relies on these fixed points of light to communicate its true size in low-visibility conditions.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003e\u003cspan\u003eClearance Lights Versus Side Marker Lights: Positioning

site, and telling them apart avoids ordering the wrong part. If the fixture in question flashes rather than stays constantly lit, it belongs in Turn Signals instead, since side marker lights and side indicator lights sit close together on many vehicles but serve entirely different functions. If you are fitting out a trailer specifically rather than a truck or fleet vehicle, our \u003ca href=\"https:\/\/cbtautoparts.com\/collections\/trailer-lights?_pos=1\u0026amp;_psq=Trailer+Lights\u0026amp;_ss=e\u0026amp;_v=1.0\"\u003e\u003cstrong\u003eTrailer Lights\u003c\/strong\u003e\u003c\/a\u003e range covers the broader lighting kit, while this page focuses on the marker and clearance function specifically.
