Just installed LED turn signals and now they flash way to fast or not at all? Do you have "bulb out" warning lights? We have you covered. If at all possible, it is best to use an LED compatible flasher relay. But sometimes due to complicated electronics, like a CANbus system, it just isn't an option. With no removable flasher relay, you are forced to "trick" the system into thinking everything is normal. If that's the case, these Resistor Modules will almost certainly fix your issue.
