Blinkers are part of the automotive lighting system. The functions of this system is to provide light especially at night, to improve the visibility of the vehicle, and to relay information about the presence, position, size, and direction of travel of the vehicle, as well as the driver's intentions regarding direction and speed of travel.
If one or both of the blinkers in your car goes out, there is a need to replace them immediately, but there is no need to bring the car to a mechanic. We can try replacing the blinker bulb at home in order to save time, energy and money. We should seek for professional help only when the blinker problem is not solved even if we replaced the bulb.
For changing a car blinker, we need a screwdriver, a rag, and a blinker bulb that will replace the old one. First, we remove the plastic lens that covers the blinker using the screwdriver. Next, we need to grasp the bulb then turn it counterclockwise until it comes out of the socket. We can use the rag to create a cushion for our hands. Then, we simply turn the new bulb clockwise in order to secure it to its socket. We replace the plastic lens with a screw driver, and then we can test if the new bulb works.
