What are the reasons for the turn signal flashing too fast?

[GenevieveLynn]

The main reasons for the car's turn signal flashing too fast are: 1. Burned-out turn signal. Generally, turn signals such as the turn signal, front fender light, cornering light, rear turn signal, etc., any burned-out bulb may cause the flashing frequency to be too fast when turning. 2. Poor contact of the turn signal: such as loose bulbs, poor plug connections, etc. 3. Faulty bulb control relay: the relay controlling the turn signal light system circuit may cause this. 4. Faulty lighting circuit: poor circuit connections, poor grounding, incorrect bulb installation, rust, and other reasons.
