What is the flashing frequency of turn signals?
2 Answers
The flashing frequency of turn signals is approximately once per second. Reason for flashing once per second: When the turn signal clicks three times, it corresponds to 3 seconds in duration. This is because the normal flashing frequency of the turn signal relay is approximately 1 Hz, which equates to 60 flashes per minute, or about one flash per second. Reasons for abnormal turn signal flashing: Turn signals serve as warning indicators during turns, alerting surrounding vehicles of the intended direction change. Typically, turn signals and hazard warning lights share the same bulb. If the flashing frequency suddenly increases, it may indicate a malfunction in one side of the turn signal or its circuit.
The flashing frequency of turn signals is generally between 60 to 120 times per minute, which is approximately one to two flashes per second, a commonly adopted standard in many regions. Having driven numerous vehicles, I find this frequency quite appropriate: flashing too slowly may be easily overlooked by other drivers, while flashing too rapidly can be distracting or irritating. International regulations such as ECE or FIA have stipulations, but specific models may vary slightly by a flash or two. If the turn signal flashes abnormally fast, it often indicates a burnt-out rear bulb or a short circuit causing increased current; if it flashes slowly or not at all, possible causes include a blown fuse, relay malfunction, or poor switch contact. For driving safety, it's advisable to promptly inspect or visit a repair shop when encountering such issues, avoiding delays that could compromise turn signal clarity. During normal use, developing the habit of frequently checking dashboard indicator lights to ensure proper turn signal operation is crucial.
