18 LEDs illuminate a bright white running light, then flash as an amber turn signal. When the turn signal is activated, the white light remains off to provide a full contrast left and right turn signals. Mounts to the vehicle with provided hardware, and also has double-sided tape for added security. 6′ wire leads exit the back center of each unit and are pinned for use with provided quick connectors. With connectors installed, lights are plug and play with Custom Dynamics SXS Turn Signal Module part # 2050-0449 and SXS Turn Signal Switch part # 2106-0582 (sold separately). Works on all 12 V DC systems.
