What may be a cause of a significantly increased flashing frequency of the turnsignals?
Show the correct answer
Correct answer
B. A failure of one of the turnsignal bulbs.
Explanation
In the photo you can see part of the dashboard with the fuel gauge and the green warning light (indicator light) for the left indicator. Much faster flashing of the indicators usually means a failed bulb in one of the indicator lamps - answer B. A short circuit (A) would rather switch the circuit off, and low battery voltage (C) does not make the flashing faster.
The indicator relay is built so that when less current flows through the circuit - because one bulb has blown - it starts switching twice as fast, warning the driver of the fault; you can also hear this in the faster ticking. The Regulation on the technical conditions of vehicles requires a motor vehicle to have indicators in working order, and the Road Traffic Act requires you to signal in advance your intention to change direction or lane. With one dead lamp other drivers cannot see that you intend to turn, so you replace the bulb immediately - it costs only a few PLN.
