What is the reason for the rapid flashing of the Sylphy's turn signal after it is turned on?
2 Answers
Sylphy turn signal flashes quickly after turning on the reasons: 1. Any one of the turn signal bulbs is burned out; 2. Poor contact of the turn signal, such as loose bulbs or poor plug connection; 3. Inconsistent power or model of the turn signal bulb, when replacing the turn signal bulb, the same specification model bulb is not used, or the power is too large or too small; 4. Failure of the bulb control relay; 5. Poor connection of the light circuit or poor grounding; 6. Incorrect installation of the bulb. The Sylphy is a compact car under Dongfeng Nissan. Its body length, width and height are 4631mm, 1760mm, 1503mm respectively, and the wheelbase is 2700mm. The front suspension of the car is MacPherson independent suspension, and the rear suspension is torsion beam non-independent suspension.
Once when I was driving my Nissan Sylphy, I noticed the turn signal was blinking unusually fast, which startled me. This is most likely caused by a burnt-out turn signal bulb—when one bulb fails, the current becomes unbalanced, causing the signal to flash faster. It could also be due to poor wiring contact or a short circuit, making the system think there's no load. Sylphy owners should pay extra attention to this issue, as many have encountered it. I tried replacing the bulb myself: open the engine compartment, locate the front or rear light housing, unscrew the cover, and inspect. If the filament appears blackened, it's definitely blown—just replace it for a few bucks. But if the fast blinking persists after replacement, it might be a faulty flasher relay or aging wiring harness, in which case a visit to the repair shop is necessary. Never delay fixing this, as faulty turn signals are dangerous—other drivers might misjudge your turning intentions, increasing collision risks. Regular maintenance of the lighting system is best to prevent such minor issues and ensure driving safety.
