FLASHER (Komatsu KO3EB-55-A5610)

A damaged flasher can interrupt the turn-signal or hazard-warning circuit, leaving the operator without visible directional indication. During inspection, a flasher may fail to produce the characteristic on-off cycling, causing the signal lights to remain steady or dark. Flasher condition affects the timing of the lamp circuit, which relies on a bimetallic strip or electronic timer to create the blinking pattern. Keeping a flasher in sound condition helps maintain consistent signal timing and prevents a stuck relay from draining the battery. This aftermarket replacement part references the Komatsu catalog number KO3EB-55-A5610. Verify the serial number or application, then call (562) 693-7748.
