Do you meet the led turn signal light blink fast or hyper flash? No worries, here are easy solutions. The led bulbs hyper flash due to led bulbs draw much less current than stock lamps, this will cause a sudden drop in the circuit’s resistance causing the hyper-flash or rapid blinking of the turn signals.
2. Install the led flasher relay. Most vehicles are equipped with the flasher relay, yet it only works for the stock incandescent/halogen lamp, not for led bulbs. For led bulbs, please replace the flasher to led flasher relay to avoid it.
Firstly, Locate the vehicle’s relay cluster by checking your car’s owner’s manual, or switch to signal model to hear the click noise where the relay locates. Secondly, Locate the signal relay by checking the clicking noise comes from Thirdly, Remove the stock flasher relay and replace it with a new LED flasher relay.
3. Install the directly plug and play load resistor, usually for BA15S / 1156 / 7506, BAY15D / 1157 / 2057 will be good suggestion, yet for T25 / 3157 / 3156 and T20 / 7443 / 7440 are careful, for T25 & T20 base have 2 types socket: standard and CK/ SRCK socket, if the load resistor only compatible with standard socket, but you install them at the CK socket, it will pop out the fuse and led bulbs.
