CARROFIX Non-Powered Taillight Converter — 20in Leads, 60in 4‑Flat Extension, Weatherproof

CARROFIX Non-Powered Taillight Converter adapts vehicles with separate turn and stop light circuits into a standard 4-wire trailer harness without drawing power from your vehicle’s lighting system.

This compact, passive converter provides an easy wiring bridge for cars that use separate stop and turn signals (3-wire systems) so trailers expecting combined stop/turn circuits (2-wire systems) work correctly. It comes with 20" color-coded leads and a 60" 4-flat plug extension to reach most trailer connections, plus a weatherproof build and dust cover for long-term reliability.

How does this converter handle vehicles that separate brake and turn signals?

The CARROFIX unit passively merges separate brake and turn circuits so the trailer receives the correct combined signals without requiring power from the converter itself. It uses internal electronics to combine inputs and deliver the proper outputs to the trailer harness.

• Accepts three-wire vehicle inputs (separate turn and brake feeds)
• Outputs a standard 4-flat trailer signal (tail, left, right, ground)
• Rated to power up to 2.1 amps per output for bulbs and compatible LED loads
• Works without an external power source or battery

Will it work with LED trailer lights or only incandescent bulbs?

The converter is designed to be LED-compatible and will function with both LED and incandescent trailer lamps. In some installations with low-load LED circuits, a separate heavy-duty flasher or load resistor may be recommended to correct rapid flash rates, but that accessory is not included with the converter.

• Compatible with LED and incandescent trailer lamps
• Can require an additional flasher or resistor for some LED setups
• Maintains original vehicle light operation while supplying trailer signals

What are the physical features and how easy is the installation?

The unit includes 20" color-coded leads for quick identification and a 60" 4-flat plug extension to reach a trailer connection without stretching. The housing is weatherproof and fitted with corrosion-resistant terminals plus a dust cover to protect the plug when not in use.

• 20" color-coded wire leads: white ground, green right, yellow left, red brake, brown tail
• 60" 4-flat extension for greater reach to trailer couplers
• Double-bolted, weatherproof construction and corrosion-resistant terminals
• Includes quick-connect clip and zip-ties for tidy routing

How reliable is the connector in wet or dusty conditions?

The converter was built to withstand typical road conditions: a sealed housing, corrosion-resistant contacts, and a dust cover keep contaminants out of the plug when it’s not connected. Proper mounting and occasional inspection ensure long life and consistent signal transmission.

• Weatherproof housing to limit moisture intrusion
• Corrosion-resistant terminals for stable electrical contact
• Dust cover included to protect the 4-flat plug when unused
• Sturdy mounting points to secure the unit under the vehicle or near the hitch

Who is this for? The CARROFIX Non-Powered Taillight Converter is for vehicle owners and DIY installers who need a simple, passive solution to connect trailers to vehicles with separate turn and brake signals. It's well suited for light-duty towing where a compact, weather-resistant converter is preferred and where you may already use LED or incandescent trailer lights. If your trailer’s LEDs flash too quickly, pair this converter with a dedicated flasher or load resistor to stabilize the blink rate.
