Things You'll Need:
- Spare replacement bulbs
-
Step 1
Check the lights to see if they are working. Car lights are there for a reason. If they don't work, it's dangerous.
-
Step 2
Determine if the weather requires your car lights to be on. If it's foggy, dusk, rainy or snowy, drive with your car lights on low beam.
-
Step 3
Select high beam lights when you are on the road without oncoming traffic. Switch your car lights to low beam when you meet a car on the road.
-
Step 4
Decide if you want to have your car lights come on automatically when the lighting changes from bright to dark. Many newer cars have a setting that decides when the car should have its lights on or not.
-
Step 5
Repair any broken tail, brake or headlights as soon as they are broken. A broken light is a reason for police to pull you over and it can cause an accident.
-
Step 6
Make sure that the battery is fully charged and providing enough strength for total brightness.
-
Step 7
Scrub corrosion off battery terminals and check cables. A good connection with the battery is essential for headlights and brake lights.
