If you leave your standard bulbs in your Turn Signals (front of your mirrors) you will be OK. If you change out your Bulbs to LED (Switchback) you will need to install a
LED Flasher. If you do want to install LED Switchback I strongly recommend the
Pathfinder LED's that we sell. I have tried several versions, with none as bright as the Pathfinder. Most use half the LED's for White and Half for Amber so none are on all the time.
