Hi Nor Nazia,

the most common reason that a signal blinks faster is caused by a bad bulb. If there is a lack of voltage in the car, the signal is likely to blink fast as well.

Here are some suggestions to resolve the issue:

1. Check all wiring for damages

2. Clean turn signal components and surrounding areas

3. Change fuses

4. Test or replace the vehicle’s battery

5. Replace bulbs
