Most engines produce their peak power and torque when they approach the red line and continually driving a car within this range is critical to deliver best performance. This is where shift lights are useful, ensuring you don’t change gear too early and lose your engine’s optimum power delivery. The Shift Light Pro comes with a single 10 mm ultra bright 3000 mcd LED that lights when a pre-determined rev limit is reached. The unit can also drive an external lamp or buzzer. The rev limit is set by buttons on the front of the unit. Resolution is just 100 rpm, which allows optimum use of any engine’s power curve. The LED can be seen in direct sunlight and is easily mounted in a dash panel.
Suitable for 2, 4, 6 or 8 cylinder that use points, electronic ignition or an ECU.
