CARROFIX Non-Powered Taillight Converter — 20-inch Leads & 60-inch 4-Flat Extension, LED Compatible

CARROFIX Non-Powered Taillight Converter adapts vehicles with separate turn and stop circuits to standard 2-wire trailer lighting systems using 20" leads and a 60" 4-flat extension.

If your vehicle has independent stop and turn circuits (a 3-wire setup) but your trailer expects a combined stop/turn signal on each side (a 2-wire system), this CARROFIX converter makes the electrical transition simple and reliable without drawing power from your vehicle’s battery. It preserves your vehicle’s existing light functions, is compatible with LED and incandescent trailer lamps, and includes a long 60" 4-flat extension so you can reach the trailer plug from a variety of hitch positions.

How does this converter work with vehicles that have separate turn and brake circuits?

The unit electronically merges separate turn and brake inputs into the combined signals most trailers require. It detects the vehicle’s right and left turn signals plus the brake signal, then sends a synchronized output to the trailer’s combined circuits—without needing an external power source.

• Accepts separate stop/turn inputs (3-wire vehicle systems).
• Outputs combined stop/turn signals for left and right trailer lights.
• Non-powered design requires no extra battery or wiring harnesses.

Will this converter work with LED trailer lights and incandescent bulbs?

Yes—CARROFIX engineered this converter to be LED-compatible while still functioning with traditional incandescent bulbs. It supplies up to 2.1 amps per output, which covers common trailer lighting; if your setup causes rapid flash rates, a heavy-duty flasher (sold separately) may be required for the vehicle side.

• Rated for LED and incandescent trailer lights.
• 2.1 amps available per output for standard lamp loads.
• Option to add a heavy-duty flasher if hyper-flashing occurs.

What connectors, leads, and protections are included for installation?

The kit ships with 20" color-coded vehicle leads and a 60" 4-flat plug extension so you can easily reach and connect the trailer end. The housing uses corrosion-resistant terminals and includes a dust cover to keep the plug clean when it’s not connected. Quick-connect clip and zip-ties are included for tidy routing and strain relief.

• Color-coded wires: white (ground), green (right turn), yellow (left turn), red (brake), brown (tail).
• 60" 4-flat extension for flexible reach to trailer plug.
• Durable, weatherproof housing plus dust cover and mounting clip.

How do I install the CARROFIX taillight converter and what should I check after wiring?

Installation is straightforward: match the color-coded leads to your vehicle’s taillight wires, mount the converter in a dry accessible spot, run the 4-flat extension to the trailer, and secure cables with the included zip-ties. After wiring, test each function—running lights, brake lights, left and right turns—on both the vehicle and the trailer before hitting the road.

• Connect color-coded wires to corresponding vehicle circuits and ground properly.
• Mount converter away from heat and moving parts; use included clip and ties.
• Test running, turn, and brake lights on both vehicle and trailer after installation.

Who this product is for: This CARROFIX converter is aimed at vehicle owners who tow trailers that use a combined stop/turn wiring scheme while their tow vehicle has separate circuits—common among older cars, some European models, and specialty vehicles. It's ideal for DIY installers, RV and trailer owners, small utility trailer users, and anyone needing a compact, weatherproof way to bridge wiring differences without adding power supplies or complex modules.
