What Causes the Car's Turn Signal to Flash Too Fast?

[PaulRose]

Reasons for the turn signal flashing too fast include burned-out turn signal bulbs (on the same side), poor contact in the turn signal, or inconsistent bulb power or model. Details are as follows: Burned-out turn signal bulbs (on the same side): Common turn signals such as the right front turn signal, right front fender light, cornering light, or right rear turn signal—if any bulb is burned out, it may cause the flashing frequency to increase during turns. Poor contact in the turn signal: Such as loose bulbs or poorly connected plugs. Inconsistent bulb power or model: This occurs when replacing turn signal bulbs with non-specification bulbs, or bulbs with excessive or insufficient power.
