How Many Seconds Does the Turn Signal Exceed to Be Unqualified?

[LilahRose]

Turning on the turn signal for more than 20 seconds is unqualified. The function and working principle of the turn signal are introduced as follows: Function of the Turn Signal: As a signal light, the turn signal mainly serves to alert surrounding vehicles during daily driving, indicating an upcoming turn or lane change, prompting other vehicles to yield and avoid collisions. Whenever a vehicle needs to steer away from its current lane, the turn signal should be activated in advance, which is a fundamental principle of safe driving. Working Principle of the Turn Signal: The turn signal's lamp tube uses a xenon lamp tube, controlled by a single-chip microcomputer circuit, with left and right alternating flashes operating continuously. When a certain voltage or current is applied to both ends of the electromagnetic relay coil, the magnetic flux generated by the coil passes through the magnetic circuit composed of the iron core, yoke, armature, and working air gap.
