TST Nexus LED Front Turn Signals for Kawasaki Ninja 400 2018-2023

Our TST Nexus LED Turn Signals represent the pinnacle of TST design, combining years of development with Kawasaki’s sportbike styling language to deliver a signal kit that stands out in both performance and aesthetics. Engineered specifically for the Ninja 400, these signals offer a premium factory-fit appearance with modern LED technology and unmatched attention to detail—right down to the texture-matched polymer alloy housings.

Choose from standard or sequential signal options, and decide whether you want to incorporate a running light function for added visibility. Select models feature a sequential turn signal pattern with an integrated running light, giving you even more customization and a striking visual effect. Installation is simple thanks to plug-and-play style connectors and comprehensive step-by-step video guidance. With three configuration options available, you can tailor the setup to match your riding style and budget while transforming your Ninja 400 with lighting performance you won’t find anywhere else.

Running Light:
Kawasaki’s front signals do not include a running light circuit from the factory, but we provide all necessary components to add this functionality without special tools. Sequential Nexus signals always include the running light feature and do not require a sub-harness. If you choose not to use the running light, simply insulate the blue wire and leave it disconnected.

Flash Rate:
To ensure proper flashing, an LED flasher relay is required. If your bike is not yet equipped with one, our plug-and-play TST Gen2-F LED Flasher Relay is recommended for optimal function.
