DOT-Compliant LED Tail Light for Wide Trailers – Left Side (Roadside)
The Anderson M856L is the left-side (roadside) LED combination tail light designed for trailers 80 inches wide and over. It combines stop, turn, tail, and side marker functions into a single sealed unit, and includes an integrated license plate light — making it a complete rear-left lighting solution in one fixture.
Built to directly replace 456-series incandescent lights, the M856L upgrades your trailer to long-life LED performance without requiring bracket or wiring changes. Fully submersible construction with potted circuitry protects against moisture, corrosion, and vibration — suited for boat trailers and any application with regular water exposure.
Key Features
- Combination stop, turn, and tail light in a single unit
- Integrated license plate light (M856L roadside/left side)
- Dedicated side marker diode built in
- Fully submersible — potted circuitry resists moisture, corrosion, and vibration
- 100,000-hour LED rated life — no bulbs to replace
- Lower current draw than incandescent equivalents
- Direct replacement for 456-series incandescent lights
- Exceeds all DOT rear lighting and reflex requirements for trailers 80" wide and over
- SKU: 177-V856L
Best Use Case
The go-to choice when replacing just the left rear light on a wide trailer — boat trailers, equipment trailers, or utility trailers 80" wide or wider. The integrated license plate light makes this the correct left-side choice; the right side does not include a license light.
Parts Desk Insights
This is the left (roadside) unit only. For a matched pair, add the Anderson LED Over 80" Wide Combination Tail Light, Right – 177-V856. If you need a complete rear lighting system with all required DOT components, the Anderson LED Over 80" Wide Rear Trailer Light Kit includes both lights plus the license bracket and mounting hardware. For a submersible combination light with a different form factor, also consider the Anderson E452L Over 80" Submersible Combination Rear Light with License Plate Illuminator.
