Some vehicles require the stock flasher relay to be replaced with an LED relay to fix ‘hyperflash’ when adding aftermarket headlights with turn signal, adding LED indicators, or swapping halogen bulbs for LED. If your vehicle uses a flasher relay rather than control through the BCM, then one of these LED specific flasher relays will rectify the hyperflash.

Available for a range of vehicles. Just check what type of relay your car is using.

CF18 for some Subaru, Toyota and Lexus

CF14/EP35 for some Volvo, Audio, BMW, Chevrolet, Ford, Mitsubishi, etc

EP27 for some Chrysler, Dodge, Ford, Jeep, Lincoln, Mazda, Pontiac, etc
