This add-in circuit enables the Z-Flex strip to work like a 1157 bulb. So, the light will be a running and brake light or a running and turn signal indicator.

Aka: changing the light from a 2 wire setup to a 3 wire setup for running light and brake light

Figure out how many LEDs will be used and choose the dual-element circuit that will work.

5-10 LEDs – Part Number 6123-00

15-25 LEDs – Part Number 6120-00

30-60 LEDs – Part Number 6122-00

65-125 LEDs – Part Number 6121-00

130-150 LEDs – Part Number 6124-00
