The shift light illuminates when the engine speed reaches preset maximum rpm.

The shift light illuminates when the engine speed reaches preset maximum rpm.

• A. True
• B. False
• C. Only during startup
• D. Never

Answer: (A)

Shift lights are visual cues tied to engine speed. They are wired to the engine’s RPM signal and programmed with a specific threshold. When the tachometer hits that preset maximum RPM, the light turns on to tell you it’s time to shift. This helps prevent over-revving and aims for an optimal power band, often slightly below the redline to give you a clean shift. It isn’t related to startup, and it isn’t something that never happens; the light is specifically there to illuminate at that chosen RPM.
