Square LED Side Marker Light / Clearance Lamp

The Universal Square LED Side Marker Light is a heavy-duty clearance lamp engineered to provide exceptional nighttime visibility and safety compliance for large commercial and recreational vehicles. Utilizing advanced solid-state LED arrays encapsulated beneath a faceted, light-diffusing lens, this lamp produces a bright, wide-angle illumination profile that remains highly visible even through heavy rain, fog, and dust storm conditions. The unit is designed for flat-surface flush mounting along the sides, roofs, or rear panels of vehicles to clearly delineate vehicle length and height boundaries to surrounding motorists.

A standout engineering aspect of this model is its rear-facing plug base, which features high-purity copper wiring terminals for low electrical resistance and long-lasting corrosion protection. The flat blade contacts include integrated structural ring holes, allowing for quick solder bonds, secure crimps, or direct matching harness plug insertion. Encased in a rugged, impact-resistant ABS composite chassis paired with a sonic-welded acrylic lens, this weatherproof marker lamp handles the extreme vibrations, road salts, and thermal fluctuations common to long-haul shipping routes.

• High-Conductivity Copper Wiring: Features premium copper terminal prongs that maintain low electrical resistance, resist oxidation, and ensure a stable connection.
• Faceted Light-Diffusing Lens: Formed with specialized internal geometric facets that bend and amplify LED light beams, expanding multi-angle visibility across a 180-degree field.
• Easy Surface Mount Installation: Low-profile plug-in base design simplifies vehicle routing, allowing you to pass the socket housing directly through a standard pilot hole.
• Weatherproof Sealed Architecture: Sonic-welded structural joints prevent moisture ingress, protecting the underlying circuit board from premature failure due to rain or high-pressure power washes.
• Universal Commercial Fleet Compatibility: Fits seamlessly onto flatbed trucks, cargo box trailers, livestock transport haulers, RV motorhomes, pickup trucks, and heavy-duty utility equipment.
