Allows for up to 5 separate turn signal segments per side to flash sequential instead of flashing all at the same time. Optimal sequential flash speed is programmable via dip switches depending on the number of LED segments desired. Equipped with running light output control wire to shut off the running light output when the turn signal sequence is activated to provide maximum visibility when dual color (i.e. amber/white) LEDs are used. Left and right side plug and play quick connectors included. 9-16 VDC operating range.
