There are a range of parts on your Mercedes-Benz designed to allow other drivers on the road know your location. Things like the lights on your car are designed to make it easier to see where you are on the road. The turn signals on your vehicle are a part of this system and alert other drivers when you are wanting to switch lanes or make a turn. The turn signal lights are located both on the front and back of your vehicle. They are operated by the turn signal switch. When you flip one of the switches, your turn signals will flash until you complete the turn or you switch them off manually. There are some ways you can tell if the turn switch signal is wearing out. If it continues blinking even once your steering wheel is back to a center position, then there could be an issue. Your turn signals might not flash unless you hold down the lever. If you need replacement turn signal lights or a switch itself, find the right OEM Mercedes-Benz parts here on our site.
