Buyers Products Company 7-Way Trailer Connector Strobe Kit TC8891 — 12V Remote-Controlled, Magnetic Mount

The Buyers Products TC8891 Trailer Connector Strobe Kit is a 12V plug-and-play device that connects into a standard 7-way trailer connector to momentarily strobe compatible LED trailer lights for increased roadside and worksite visibility.

When you need extra visual warning for a stopped or slow-moving trailer, the TC8891 provides a quick, non-invasive solution. It plugs between your truck and trailer 7-way connector and triggers compatible LED lights to flash in selectable patterns, without cutting or reworking existing wiring. Built to withstand outdoor conditions and everyday fleet use, this kit balances ease of installation with practical visibility features that support safer roadside, marine, and worksite operations.

How does the TC8891 install and start working?

Installation is designed to be fast and reversible. The unit plugs directly into standard 7-way RV and round-pin trailer connectors, sitting inline between tow vehicle and trailer so no additional wiring or splicing is required.

• Plug-and-play: connects to existing 7-way connectors in seconds
• No permanent wiring: removable unit leaves trailer wiring unchanged
• 12V operation: uses the vehicle's trailer power circuit
• Mount options: magnetic base or zip-tie attachment for stability

What control options and flash patterns are available?

The kit includes a wireless remote that lets you activate the strobe from the cab and switch among six distinct flash patterns. This lets operators pick a pattern appropriate to the situation—steady warn, slow flash, rapid strobe, and more—without leaving the vehicle.

• Wireless remote: activate or change patterns from the cab
• Six selectable flash modes: choose intensity and rhythm
• Momentary or continuous activation depending on chosen pattern
• Remote range suitable for standard towing operations

Which trailers and lights are compatible with the system?

The TC8891 is made to work with trailers using standard 7-way connectors and LED lighting circuits that accept pulsed input. It is not a replacement for permanent emergency lighting but a supplemental strobe controller that increases attention to the trailer when needed.

• Compatible with 7-way RV, OEM, and round-pin trailer connectors
• Designed for trailers equipped with LED taillights and marker lights
• Works for utility, equipment, cargo, marine, and RV applications
• Not intended to replace regulated emergency vehicle lighting systems

How durable is the unit for outdoor and fleet use?

The device is engineered for rugged environments with a die-cast housing and an IP65 rating to resist dust and water exposure. Combined with magnetic and zip-tie mounting options, it offers a practical, temporary install that stands up to road spray and jobsite conditions.

• Die-cast metal housing for impact and corrosion resistance
• IP65 weather resistance: protected against dust and low-pressure water jets
• Magnetic base for quick attachment and removal on steel surfaces
• Zip-tie mounts available for non-magnetic or permanent positioning

Who is this for: The TC8891 is suited to fleet managers, contractors, truckers, RV owners, boat haulers, and anyone who needs an easy-to-install visibility aid for trailers. It’s especially helpful for operators who want a non-destructive, reusable way to enhance attention during roadside stops, loading operations, low-light towing, and temporary work zones.
