A pass switch, also known as a "flash-to-pass" switch, is a feature commonly found on motorcycles. It is a momentary switch usually located on the handlebars, designed to temporarily activate the high beam headlights for improved visibility when passing or signaling other drivers.
When a rider encounters a situation where they want to quickly alert oncoming traffic or signal their intention to pass, they can activate the pass switch. Pressing the pass switch causes the high beam headlights to flash momentarily, providing a bright and attention-grabbing signal. Once released, the high beam headlights return to their normal state (on or off) based on the rider's previous settings.
The pass switch is a convenient and practical feature that allows motorcyclists to communicate their intentions effectively and enhance their visibility in situations where increased attention is necessary. However, it's important to use the pass switch judiciously and considerate of other road users, as using high beams excessively or inappropriately can be distracting or even potentially blinding to other drivers.
