A shift light is a warning lamp fitted to vehicles in order to indicate to the driver that maximum revolutions per minute (r/min) has almost been reached. Ideally a shift lamp will illuminate at the engine speed beyond that which delivers the maximum power, measured in for example kilowatt (kW) or brake horsepower (BHP), such that the power before and after shifting is the same. Accelerating the engine beyond this point is not conducive to ideal acceleration. In use a shift light allows the driver to judge the exact point that a gear change should be carried out without having to glance down at the tachometer. This also increases safety for the driver by keeping their focus near the track at all times.

| - Ein Schaltblitz ist ein System, das oft im Kfz-Bereich, besonders im Rennsport verwendet wird. In das Fahrzeug wird eine schnell reagierende Signallampe oder LED installiert, welche bei Erreichen einer Maximaldrehzahl aufleuchtet und dem Fahrer einen nötigen Schaltvorgang signalisiert. Dadurch wird dem Fahrer eine Ablenkung durch den Blick auf den Drehzahlmesser erspart. (de)
- Le shift-light (shift light, ou shiftlight, qu'on peut traduire en français par « indicateur lumineux de changement de vitesse ») est un indicateur de régime moteur lumineux présentant au conducteur d'un véhicule de façon claire la plage d'utilisation de son moteur. Des LED de couleurs indiquent la plage de régime, quand le rouge est atteint, il est temps de passer le rapport de vitesse supérieur. Cet appareil est utilisé principalement dans les sports mécaniques. (fr)

In use a shift light allows the driver to judge the exact point that a gear change should be carried out without having to glance down at the tachometer. This also increases safety for the driver by keeping their focus near the track at all times. Beginning in the early 1980s, many United States-market vehicles equipped with a manual transmission began to have shift lights as standard equipment; these would usually signal for an at an engine speed that provided maximum fuel efficiency, lower than the ideal engine speed for maximum power. The reason for this was, for a time EPA fuel economy testing rules stipulated that shift lights would be followed on vehicles so equipped- thus, they were calibrated for optimum fuel mileage on the EPA test cycle. Some in the 1980s even had buzzers to alert the driver it was at a certain r/min. Towards the late 1980s and early 1990s, shift lights saw uses in multiple motorsport disciplines, such as Formula One, to signal for an upshift at an engine speed which provided optimal power within the torque curve, ensuring optimum acceleration.
