With the “dual mode” shift light, you don’t have to watch the needle on the stock tach to try to hold the engine rpm at your desired launch rpm. Instead, program the launch rpm into the shift light with +/- rpm limits. When the rpm is within those limits, all seven leds light up. If the rpm is too low, the leds go out. If the rpm is above the upper limit, the leds blink, letting you know the rpm is too high. This can all be seen from your peripheral vision and you can stay focused on the staging lights at the track. Once the vehicle is moving, it reverts back to shift light mode and lights up at or above the programmed shift rpm. When the vehicle is not moving, it once again reverts back to launch mode. With the optional “auxiliary output” wire, you can activate or de-activate a device at the shift point. This could be an air shifter for a motorcycle, an audible alarm, etc.
