If one of your turn signal lights blinks rapidly or doesn't blink at all, what does it mean?

When a turn signal light blinks rapidly or does not blink at all, it typically indicates a problem with one of the bulbs in the system. Specifically, a rapid blink often occurs when a turn signal bulb is burned out or malfunctioning because the electrical flow is altered. This change is detected by the vehicle's flasher unit, which responds by increasing the blinking speed to alert the driver of the issue.

In this scenario, the correct answer highlights that one of the turn signal bulbs requires replacement. Addressing this will restore the proper functioning of the turn signal system, ensuring that drivers can effectively communicate their intentions to others on the road. Understanding this helps promote safe driving practices and vehicle maintenance awareness.
