PC-Rated 180° Visibility

The TecNiq S37 is PC rated, providing 180° visibility for trailer side marker and clearance lighting applications. This wider viewing angle helps improve visibility from multiple directions and can allow one properly placed light to function as both a side marker and clearance light in many trailer layouts.

Unlike traditional P2-rated marker lights, PC-rated lights provide broader visibility from multiple viewing angles. This can help improve trailer conspicuity while allowing greater flexibility when designing DOT-compliant lighting layouts.

For trailer manufacturers, repair shops, and custom builders, PC-rated marker lights are often preferred when maximum visibility is desired in a compact package.

Designed for Tight Installation Spaces

One of the biggest advantages of the TecNiq S37 is its ultra-compact design. These miniature 3/4″ LED marker lights feature approximately half the installation depth of many traditional 3/4″ marker lights, making them an excellent solution when space behind the mounting surface is limited.

This shallow-profile design allows installation in trailer frames, enclosed trailer walls, truck bodies, toolboxes, aluminum extrusions, and other locations where larger marker lights may not fit. Builders and repair shops frequently choose the S37 when maximum visibility is required in the smallest possible package.

Compact 3/4″ Grommet-Mount Design

The S37 installs into a standard 3/4″ mounting hole using the included S33-0G00-1 black rubber grommets. Its miniature design provides a clean OEM appearance while allowing installation in locations where larger marker lights may not fit.

Multiple Lens and LED Color Options

This S37 listing allows you to choose the correct light configuration for your trailer or vehicle application. Options include amber lens with amber LED, clear lens with amber LED, red lens with red LED, clear lens with red LED, clear lens with white LED, and clear lens with blue LED.

Built for Harsh Trailer Environments

Featuring IP68-rated waterproof construction, TecSeal urethane-potted electronics, and automotive exterior-grade polycarbonate construction, the TecNiq S37 is designed to withstand vibration, moisture, road spray, dust, mud, and demanding outdoor use.

Long-Life LED Performance

TecNiq S37 LED marker lights are designed for long service life and dependable visibility while consuming minimal power. These lights are a strong choice for trailer repairs, fleet maintenance, lighting upgrades, and new trailer builds.
