22 Sun Light Wireless Tow Light Bar with 4 Pin Flat Transmitter

Our review of the 22 Sun Light Wireless Tow Light Bar finds it best suited for drivers who need a simple, portable warning light for occasional towing and trailer work. The single biggest reason to buy is the ease of use: a wireless design with powerful LEDs and strong pull magnets means setup is just place and go, no wiring required. For someone who wants clear stop, tail, and turn signals without a permanent vehicle install, this unit delivers straightforward functionality and reliable brightness.

Key Features

• 22 in light bar: Provides a compact, visible warning strip that fits small trucks, SUVs and trailers without obstructing rear windows.
• 14 LEDs for stop, tail and turn: Delivers clear signaling that improves visibility to following traffic in daylight and at night.
• Wireless operation: Eliminates the need to splice into vehicle wiring, making setup and removal fast and simple for occasional use.
• 4 Pin Flat Transmitter included: Ensures direct connectivity to a trailer or vehicle connector for consistent signal transmission.
• High capacity battery: Built-in battery provides extended runtime for long jobs and reduces the need for frequent recharging.
• 90 lb pull magnets with rubber boots: Strong magnetic mounting holds the bar in place on metal surfaces while rubber boots protect paint.

Who It's For

This tow light bar is ideal for weekenders, DIYers, and small business owners who tow occasionally and need a portable light solution without permanent modification. The wireless setup and included transmitter make it a practical choice for people who swap the light between vehicles or trailers.

It is less well suited for users who require an integrated fleet tracking or reminder system, since this basic TM22Y unit is not compatible with the iMON reminder system and is non-upgradeable. Heavy commercial users who need replaceable modules or advanced connectivity should consider a different, upgradeable model.
