Tow Ready Tail Light Converters

Tow Ready Tail Light Converters: Bridging the Gap Between Tow Vehicle and Towed Car

When you hook a car up behind a motorhome or RV for flat towing, one of the most critical — and most overlooked — electrical challenges is the lighting mismatch between the two vehicles. Most RVs and motorhomes use a combined 2-wire lighting system, where a single circuit handles both the brake signal and the turn signal. Many passenger vehicles, on the other hand, use a separate 3-wire system with independent circuits for each function. Without a proper converter in between, your towed car's brake lights and turn signals simply won't work correctly — a serious safety and legal problem on any public road.

That's exactly the problem that Tow Ready tail light converters are engineered to solve. As part of the broader Cequent family of towing brands — which includes Draw-Tite, Reese, and Tekonsha — Tow Ready draws on decades of towing industry expertise to produce wiring solutions that are both dependable and straightforward to install.

What Sets Tow Ready Apart in Tail Light Conversion

Tow Ready's tail light converters are built around solid-state electronics, which means there are no mechanical relays to wear out or fail over time. This design translates to consistent signal conversion and dependable performance mile after mile. The converters feature color-coded wiring that takes the guesswork out of installation — each wire corresponds to a clearly defined circuit, so even a first-time installer can complete the job with confidence.

The flagship model 118158 is a 2-to-3 wire tail light converter purpose-built for flat towing applications, ensuring that brake and turn signals from the motorhome appear correctly on the towed vehicle. It is specifically designed for vehicles equipped with incandescent tail lights and is backed by a limited warranty for added peace of mind.

Tow Ready also offers the model 119130, a taillight converter with a 4-Way flat end that adapts domestic and import vehicles with separate turn and stop lights (3-wire systems) to standard trailer taillight wiring (2-wire systems). Notably, this converter is compatible with most LED, incandescent, and standard bulbs, and works with most vehicles' multiplex wiring systems for lighting — making it a versatile choice for a wide range of tow setups.

Why Proper Tail Light Conversion Matters

Operating a towed vehicle without functioning brake and turn signal lights is not only dangerous — it can expose you to traffic violations and liability. A quality tail light converter ensures that every braking event and every lane change is clearly communicated to traffic behind you, protecting both you and other drivers on the road. Tow Ready's converters are designed specifically for the demands of flat towing, where the electrical systems of two separate vehicles must communicate seamlessly at highway speeds.

• 2-to-3 Wire Conversion: Translates combined RV lighting signals into the separate brake and turn circuits required by most towed passenger vehicles
• Solid-State Construction: Trouble-free electronics deliver consistent performance without mechanical wear
• Color-Coded Wiring: Simplifies installation and helps ensure correct connections every time
• Broad Compatibility: Options available for incandescent systems as well as vehicles with LED or multiplex lighting
• Flat Tow Ready: Engineered specifically for motorhome and RV flat towing applications

Whether you're a full-time RVer or an occasional road tripper who flat tows a second vehicle, Tow Ready's tail light converters deliver the electrical reliability your setup demands.
