Truck-Lite 40830 40 Series Left Hand LED Wide Turn Signal Light - 84-Diode 12V Yellow Rectangular (Grommet Mount)

Maximize fleet safety and roadside visibility during tight maneuvers with the Truck-Lite 40830 40 Series LED Left Hand Side Wide Turn Signal. Engineered for mid-trailer or side-panel mounting on the driver side, this heavy-duty 12V yellow rectangular lamp features an oversized outer lens powered by an ultra-bright 84-diode LED configuration. Completed with an enclosed back design for maximum wire protection, a shock-absorbing black PVC grommet, and an adjustable slotted bracket, it routes power cleanly using a hardwired PL-2 to ring terminal harness.

Prevent costly "squeeze-play" roadside collisions and keep your fleet DOT-compliant with the Truck-Lite 40830 40 Series Left-Hand LED "Wide Turn" Arrow Indicator. Designed explicitly for long commercial trailers, straight trucks, and vocational fleets, this mid-ship auxiliary turn signal flashes boldly with a left-facing arrow graphic to warn adjacent motorists and blind-spot drivers when your vehicle establishes a wide left turn.

This premium safety lamp utilizes an advanced 84-diode LED array that triggers instantly, offering crisp visibility that far outlasts and outperforms traditional incandescent versions. The 40830 model is built with a rugged enclosed-back housing that creates a solid structural armor shield around rear wire connections, insulating your electrical paths from moisture, road salt, mud, and high-pressure trailer washes. Both the housing and the large rectangular yellow lens are molded from high-impact, scratch-resistant polycarbonate to prevent cracking and fading.

For quick retrofitting, the unit is shipped with an open-back black PVC vibration-damping grommet (Common size 7"x13") and an adjustable slotted L-bracket to ensure precise flush mounting. The pre-wired, heavy-duty 14-gauge harness uses a standard 2-prong PL-2 pigtail connector coupled with a ring terminal ground lead for stable grounding.
