Building on the popularity of their LED Turn Signal Kits, Yoshimura now introduces sequential LED Turn Signal Kits. Both front and rear sequential kits are two-wire configuration and can be mounted on most of today's motorcycles. New Sequential Front Kit contains: CE Certified set of sequential two-wire LED lights with a clear lens, anodized black aluminum body in a rubber-insulated mount to decrease vibration. Mounting hardware. Note: The Yoshimura Diode Kit (sold separately) may be required when using LED turn signals. If you have a single-bulb turn signal indicator, the Diode Kit is required for proper turn signal operation. Diode Kit is designed to remedy turn signal issues where the turn signal light stays illuminated and does not flash as a result of switching to LEDs.
