When the brakes are pressed, one or both brake lights do not light up.
If both bulbs are inspected and neither show damage, then the next possibility is a blown or missing fuse. Inspect the fuse box and find the appropriate fuse for the brake light system. If it is missing, or the fuse is blown, replace the fuse.
Typically both brake bulbs will not burn out simultaneously, but it can happen. To see if the bulb is burnt out, the bulb must physically be removed from the car and inspected. If the filament in the bulb is split or damaged, use this brake light replacement guide to replace brake light bulb.
One or both headlights for the car will not turn on regardless of the switch being set to on, or it is nighttime and the automatic lights should be engaged.
Again, like the brake lights, if both bulbs are inspected and neither show damage, then the next possibility is a blown or missing fuse. Inspect the fuse box and find the appropriate fuse for the headlight system. If it is missing, or the fuse is blown, replace the fuse.
If it is suspected a bulb is burnt out, like the tail lights, the light must be removed and checked for damage. If the bulb is damaged, use this headlight replacement guide to replace headlight bulb.

Manufacturers recommend replacing your car battery every 3-4 years, but the best way to check your battery is by using a multimeter to check the voltage output.
