How to Change a Turn Signal Bulb on Vehiclesby Contributing Writer
The Vehicles is a hatchback economy car. The front turn-signal bulbs are located in the headlamp housing. The rear turn signals are located in the pillar of the hatchback door. Since working turn signals are essential to driving safely and legally, you should inspect your turn signals, and all other exterior lights, on a regular basis. If you find any turn signal bulb burned out, replace it before driving the Vehicles again.

Items you will need
Replacing the Front Bulbs
Start the car and turn the steering wheel all the way towards the opposite side of the light bulb you are replacing. If you are replacing the driver's side bulb, turn the wheel to the right; for the passenger's side bulb, turn the wheel to the left. Then stop the car. This turns the wheel so that it's not in your way.
Check under the inner fender directly in front of the tire. You should see a cover with a holding clip to keep it in place. Disconnect the holding clip using a flat-head screwdriver and then detach the inner fender cover.
Grasp the light bulb socket in the turn signal array and give it a one-quarter turn counterclockwise. Carefully pull it free.
Push the old bulb into the socket and turn it counterclockwise to disconnect it. Then pull it free.
Push the new bulb into the socket and turn it clockwise until it is secure. Replace the socket in the headlight array and turn it clockwise to set it in place.
Turn on the lights in the car without turning on the engine, and activate the turn signal. Have someone outside the car check to make sure it is functioning.
Snap the fender cover back into place and tighten the holding clip with the screwdriver.
Replacing the Rear Bulbs
Pop the trunk and remove any items that might be obstructing the turn signal array. In some models, you may need to pull the lining aside as well. (You can do this by detaching the pin holding it in place with a screwdriver.)
Grasp the turn signal light socket and turn it one-quarter of the way counterclockwise, then carefully pull it free.
Pull the bulb directly out of the socket and replace it with the new one. You can just push the bulb into place until you feel it touch the bottom of the socket interior
Put the socket back into the turn signal array and turn it one-quarter clockwise. Check to make sure it is secure.
Turn on the car's power and check to see that the turn signal is working.
Replace the items you moved and close the trunk.
