To solve the hyper flashing from the LED turn signal bulbs.
Fitment
Designed for models of Mazda except: MX-5, CX-3, CX-5, CX-7, CX-9, 2, 3, 5, 6
Note
Due to lower power consumption of LED bulb, it is more possible for it to hyper flash. The relay is a junction between power and bulb for eliminating hyper flash.
If your car issues the error noise, you will need a decoder.
