ABSTRACT:
An improved over-running indicator structure essentially comprises an upper housing, a lower housing, a circuit board and a fixing support; the upper housing and the lower housing are firmly connected by a lock device, and the lower housing is fixed on the fixing support; a circuit board is set between the upper housing and the lower housing, the circuit board is configured with a light emitter, a screen and a button, the circuit board uses a transmission line to connect with a tachometer; a driver can use the button to set the rotational speed for showing the rotational speed which is set by the driver on the screen, when the rotational speed of the engine exceeds the rotational speed that is set by the driver, the light emitter disposed on the circuit board shines and radiates the light thereof through the arc surface of the upper housing, thus, the driver feel no constrained to any angle for being readily aware of the optimal shifting time to acquire the best power from engine.
