Your car has light bulbs both at the front and the back
To begin, determine how you will access the dead bulb. You can do this alone or seek the help of a mechanic. Some bulbs are accessible from the outside while others must be accessed from within the truck.
Next, check the screws, knobs or tabs holding the outer light bulb cover. Find out how you can open the cover without breaking anything. Many cars have plastic covers that are held by screws firmly. If this applies to your car, use a screw driver to unscrew them.
After removing the outer cover, unscrew the dead bulb from the socket. Sometimes, a poor connection may be the cause of the problem. Therefore, check the connections, fix the bulb and test whether it works. If it does not light up, replace it with a new one.
Take the bulb to an auto store you and ask for a duplicate. Nearly all the bulbs have a description of their size and volts at strategic areas. The seller should be able to read and know the specific make to give you. It is advisable to pick an extra bulb just in case the one you buy fails to work.
Before fixing a new bulb, clean the socket with a wire brush. This will wipe out any rust that may have found its way into the socket. Afterwards, screw the bulb tightly to the socket. You may have to push gently as you screw to ensure it is tightly fitted.
After screwing the bulb, confirm that it is working before you replace the plastic cover. To confirm, step on the brakes and turn the headlights on as someone watches to see if the lights are working. If the bulbs work, replace the plastic cover and tightly screw back the screws.
It is essential to always check on the car lights before driving. Sometimes, a poor connection may be the cause of bulb failure. Take your car for servicing on a regular basis. Any poor connections will be easily detected and rectified before the bulbs fails.
