Description

One of the standout features of the Yamaha YZF-R9 is the aggressively styled daytime running lights (DRLs) flanking the center position headlight. They give the bike a bold and modern look that is a signature part of the Yamaha R series. But beyond the aesthetics, we saw an opportunity to boost both function and visibility. That’s why we developed the TST DRL to Turn Signal Harness Converter kit. This kit utilizes OEM-style plugs and Posi-tap connectors to ensure a hassle-free installation, enabling you to add turn signal functionality directly to your R9's DRLs. Once installed, your DRLs double as turn signals, flashing in sync with the OEM mirror turn signals and helping you stand out even more on the road.

Please note this item is not DOT approved and may not comply with the laws and regulations in your area. See our Terms & Conditions for more information.

Q: Do I have to do any wire cutting?
A: No - This kit does not require any cutting of your stock wire harness. The supplied Posi-Tap connectors enable you to splice into a wire without cutting or soldering, while the OEM-style connectors are completely plug-and-play. Please refer to our step-by-step installation video to see the exact procedure.

Q: How long will it take for me to receive this once I order it?
