Upgrade your vehicle’s towing capabilities with the Oyviny 2-to-3-Wire Trailer Tail Light Converter. This essential electrical adapter is engineered to convert a 2-wire vehicle system into a standard 3-wire configuration, effectively separating your brake and turn signal functions. Whether you are towing with a pickup truck, van, or RV, this converter provides a reliable solution for maintaining proper signaling, ensuring your trailer lights operate in sync with your towing vehicle for enhanced road safety.

Designed for durability and ease of use, the Oyviny converter is constructed from high-strength ABS thermoplastic polymer, offering the toughness required for long-term exterior use. Installation is streamlined thanks to the standard color-coded, pre-stripped wires and included wire taps, which allow for a direct splice into your existing tail light wiring. The unit features solid-state components for consistent performance and does not require a heavy-duty flasher or a direct battery connection, simplifying your setup process significantly.
