Buying advice

When choosing an automotive relay, confirm the vehicle's flasher type (2-prong vs 3-prong) and bulb type (incandescent vs LED). For LED conversions, a load-resistor or electronic flasher designed for LEDs is necessary to prevent hyper flash. Check Amazon reviews for fitment notes specific to your make and model.
