Square Trailer Tail Light – 4 Functions (Stop/Tail/Turn/License)
This square trailer tail light combines four functions into one convenient unit, making it easy to equip your trailer with all necessary rear lights. With this single assembly, your boat trailer or utility trailer will be fully visible on the road – signaling brakes, turns, and illuminating the license plate at night. The housing is designed for long-term use, and its standard size makes installation straightforward on a variety of vehicles. It’s an ideal solution for replacing a broken light or outfitting a new trailer from scratch.
The lens features a built-in reflector to enhance visibility even when the lights are off. The Square Trailer Tail Light – 4 Functions is compatible with all standard 7-pin trailer wiring systems. It is sold as an individual unit – a complete trailer setup will require two lights (left and right side). It can be mounted on either side, with the license plate window typically oriented toward the license plate side of the trailer.
- Versatile Application: Suitable for many types of trailers – boat trailers, caravans, utility trailers, flatbeds, and more. It serves as a spare replacement module or for setting up a new lighting system on a custom trailer.
- Easy Replacement: Installs quickly in place of an old or broken tail light using a few screws and standard wiring connections. No special tools or expertise required to get it working.
- Safety & Compliance: Meets road safety requirements by providing the required brake light, indicators, and tail light functions. The integrated red reflector ensures your trailer remains visible to other drivers even when the lights are off.
- Usage Tips: Use one light on each side of the trailer for full coverage. For a complete installation, pair with an appropriate 7-pin wiring harness and connectors. If you frequently submerge your trailer (for example, launching a boat), consider removing the lights beforehand or using our quick-release mounting brackets to protect the lights.
- Upgrade Options: For heavy-duty or frequent use, you may consider upgrading to our LED trailer lights – they offer even longer life and waterproof performance, ensuring maximum durability.
