How many seconds does a turn signal flash once?

[WalterMarie]

If the turn signal clicks three times, it corresponds to three seconds in time. This is because the normal flashing frequency of the turn signal relay is approximately 1 Hertz, meaning 60 times per minute, or about one flash per second. If the frequency suddenly increases, it might indicate a fault in one side of the turn signal or its circuit. Operation method of the turn signal: Generally, the turn signal switch in most vehicles is installed on the left side of the steering wheel. The operation can be summarized as "up for right, down for left"—pushing the lever upward (clockwise) signals a right turn, while pushing it downward (counterclockwise) signals a left turn. However, with advancements in automotive technology, many modern vehicles now feature a "one-touch triple flash" quick function on the hazard light switch. The driver only needs to lightly "tap" the lever, and the turn signal will flash three times before automatically turning off. This feature eliminates the hassle of manually turning off the turn signal when changing lanes or overtaking.
