Caspers Gauges

Caspers knock gauges are equipped with 9 LEDs in three colors to indicate the severity of detonation in real-time: Green=mild detonation, yellow=moderate detonation, and red=severe detonation. The center green LED is illuminated during "standby," and when detonation occurs, upper colored LEDs will display for five seconds, and then reset to standby. They can display knock during each gear change.
