When used with an ECU that has programmable outputs (such as our Megajolt ignition system) this can be used as a low-cost sequential shift light. For example if your rev limit is 6500rpm you might do the following:
- Under 5000rpm all programmable outputs off
- Between 5000 and 5500rpm user output 1 is on to turn on green LEDs
- Between 5500 and 6000rpm user output 2 is on to turn on red LEDs
- Above 6000rpm output 3 is on and turns on both red and green LEDs
Wiring information:
- White wire 12 volt positive power source
- Green wire - Switch to ground via 100 ohm resistor to turn on green LEDs
- Red wire - Switch to ground via 130 ohm resistor to turn on red LEDs
