What Causes the Turn Signal Not to Light Up and the Flasher to Buzz?
1 Answers
Turn signal not lighting up and the flasher buzzing may be due to faults such as a short circuit, faulty flasher relay, or excessive contact gap. You can open the flasher relay cover to check if the coil and resistor are intact. If the resistor heats up and the contacts fail to close, press the movable contact. If the turn signal lights up at this point, it indicates a relay fault. Adjustments should be made if the contact gap is too large. Below are the correct ways to use vehicle lights: 1. Poorly lit roads: Use high beams on roads without streetlights or with poor lighting. However, switch to low beams when meeting other vehicles or pedestrians to avoid glare. 2. When needing to read road signs: If unfamiliar with the road and needing to read signs, high beams can be used but should be quickly switched back to low beams. 3. When overtaking: Turn on the left turn signal in advance and alternate between high and low beams or honk to alert the vehicle ahead to yield. 4. When approaching corners, curves, or intersections without traffic lights: Alternate between high and low beams as a warning. 5. When driving through tunnels: Use high beams but switch to low beams in advance when meeting other vehicles. 6. In urban areas with streetlights at night: Low beams must be used. 7. In areas without streetlights at night or during dusk or dawn: Low beams must be used when driving in such conditions. 8. Obstructed visibility: During heavy fog, snow, or rain when visibility is obstructed, low beams must be used even during the day.
