Description

The Yamaha 2025+ YZF-R3 stands out with its sharp and aggressive daytime running lights positioned beside the central headlight. These DRLs add a sleek, modern edge that reflects the signature style of the Yamaha R lineup. But they are more than just eye-catching. We saw the potential to enhance both safety and functionality, which led us to create the TST DRL to Turn Signal Harness Converter kit. Developed with OEM-style and Posi taps connections, this plug-and-play solution makes installation quick and simple. Once installed, your R3’s DRLs will also function as turn signals, flashing in sync with the dedicated turn indicators to improve your visibility to those around you and making those once static DRLs more functional.
