Upgrade your Yamaha MT-03 321 (2016–2019) with the Aharon MotoLumino V2 complete sequential LED turn signal kit. This motorcycle-specific package replaces the four original front and rear indicators with compact smoked-lens LED turn signals that sweep bright amber light progressively along the lens. Developed for the 321cc twin-cylinder Yamaha MT-03 introduced in 2016, not the earlier MT-03 660 (2006–2014) or the revised 2020+ 321cc generation, it includes the appropriate Yamaha mounting plates and an MLRLS2 electronic LED flasher relay. Watch the MotoLumino V2 LED turn signal demonstration.
Why upgrade to MotoLumino V2 sequential LED indicators?
- Complete four-indicator kit: two indicators for the front and two for the rear.
- Sequential amber light: a clear progressive sweep in a compact smoked-lens housing.
- Flexible mounting stems: weather-resistant ABS indicator units with IP67 rating.
- Approval markings: the MotoLumino V2 indicator housings carry E4 markings.
- Model-matched mounting and relay: four MLAP05 Yamaha adapter plates and one MLRLS2 two-pin LED flasher relay.

No separate MLAC wiring adapter cables are included. The original Yamaha specification for this model generation uses bullet-style indicator connections. Check the wiring on the motorcycle and make or adapt suitable bullet connections as needed; this kit should not be described as fully plug-and-play. The included MLRLS2 relay is intended for the matching original relay arrangement. Disconnect power and verify the relay socket and connector polarity before installation.
