What is Turn Signal Bulb Replacement?

The turn signal bulbs are located inside the light assemblies on all four corners of the car. The turn signal switch takes the drivers input and sends power to the corresponding bulb to inform other drivers that you intend to change lanes or make a turn. Turn signals exist to alert your surroundings that your vehicle will be making a turn. When you press the lever on your steering column, front and rear turn signal bulbs flash, to let drivers around you know of your intention to make a turn. When a turn signal bulb dies, that turn signal will no longer light up. This means that your vehicle will not alert drivers in front of you or behind you that you plan to turn, which makes your vehicle a safety hazard.
