BUNKER INDUST Trailer Breakaway Kit with LED Display — 12V 5Ah Battery, Side-Mount Weather-Resistant Emergency Brake System

The BUNKER INDUST Trailer Brake Breakaway Kit is a complete emergency stop system that automatically applies trailer brakes if the trailer separates from the tow vehicle.

Designed for trailers equipped with electric brakes, this all-in-one kit includes a breakaway actuator, a maintenance-friendly 12V 5Ah rechargeable battery, a visible LED charge display and an easy-to-use activation switch. Built as a side-mount unit with weather-resistant construction, the system gives drivers an added layer of safety during towing by engaging the trailer brakes if a hitch failure or separation occurs.

How does this breakaway kit detect and stop a separated trailer?

The unit is wired into your trailer's electric brake circuit and uses the breakaway switch to sense when the trailer detaches. Once triggered, the charger transfers power from the 12V battery to the braking system until the vehicle stops or the battery is depleted.

• Breakaway switch activates the brake circuit upon separation
• 12V 5Ah battery supplies power to apply brakes immediately
• Wired inline with existing electric brake systems—no separate actuator needed

What does the LED display and push-to-test feature show?

The integrated LED panel provides a quick visual check of battery status and charging activity. Use the push-to-test button to verify full charge, charging state, or when the battery needs recharging, helping you avoid unexpected failures.

• LED colors indicate charged, charging, or low battery states
• Push-to-test lets you confirm readiness before every trip
• Visible indicator reduces guesswork during routine maintenance

How easy is it to install and maintain on a trailer?

Installation is straightforward: the kit is configured for side-mount placement and connects directly into trailers that already have electric brakes. Weather-resistant housing and corrosion-resistant components minimize upkeep, and the rechargeable battery can be serviced or replaced as needed.

• Side-mount design simplifies bracket placement and wiring runs
• Quick connections to the trailer’s existing brake wiring harness
• Durable exterior resists moisture and roadside corrosion

What’s included and how does the kit integrate with my trailer setup?

The package contains the breakaway unit, a fully compatible 12V 5Ah battery, and a breakaway switch so you have everything required for a compliant installation. It is intended to integrate into trailers already fitted with an electric brake controller and wiring.

• Complete kit: breakaway unit, 12V 5Ah rechargeable battery, breakaway switch
• Meant for trailers that already use electric braking systems
• Installation instructions and mounting hardware provided for a standard fit

Who is this for? The BUNKER INDUST Trailer Brake Breakaway Kit is suited for trailer owners, professional haulers, and caravaners who use electric brakes and want an added safety layer in case of hitch failure or separation. It’s ideal for those seeking an integrated, low-maintenance solution with clear battery status feedback and a slim, side-mount profile that fits common trailer configurations.
