SKU: FC_S4_FrontTurns Category:

This is a replacement led board for the OEM FC S4 Turn signal bulbs

The LED board Has a perimeter of leds for Running lights and the center has a sequential bar style turn signal. Turn signal speed can be adjusted to match your cars blink rate via an adjust knob on the backside.

We recommend to install load resistors on the stock harness to slow the blink rate down to normal and then plug in the new boards. Then check that they are matching your blink rate speed. You can turn the knob to speed up or slow down the sequential rate to match. Once matched, you can glue the board in place.

Minor work is needed to install. Remove the front lens and then glue the boards in place. They are made to fit the contours of the S4 lenses, but gluing will help them from rattling around.
