When you switch on your headlamps, these lamps start working, alerting oncoming vehicles of your presence and maybe saving potential dangers.  The lens and bulb are within the side marker fixture. If the lens is fractured or damaged, it's simple to replace. Many make and models of automobiles are available.  You may easily replace a broken bulb or malfunctioning component. Opening the trunk, removing the ba bulb, and installing the new one are all necessary steps to fix the vehicle's rear marker fixture. The side markers blink tandem with the turn signal to indicate a turn. This implies that you have to time when you turn them off and on carefully. In addition to increasing your vehicle's security, they also give it a more stylish appearance.
