Customized Car Flasher & Buzzer

If the occupants do not wear seat belts, the seat belt warning light and buzzer reminder device will issue a warning to remind the occupants to wear seat belts.

The results of special research on this aspect show that the seat belt reminder device has increased the wearing rate of seat belts by about 40%, which has saved the lives of many drivers and passengers.
