A Step-by-Step Guide to Fixing Your Car’s Lights

Vehicle lighting systems are crucial for safety, visibility, and legal compliance on the road. Like many auto parts, headlights, taillights, brake lights, and turn signals are subject to wear and eventual failure. Regular inspection and timely replacement of these lights are essential to ensure you can see the road clearly and other drivers can see you, especially during challenging driving conditions.

What causes headlights to go bad?

Multiple factors contribute to automotive headlight bulb deterioration. Temperature extremeswhether scorching summer heat or freezing winter coldcan significantly accelerate bulb degradation. Even though headlight housings are designed to be sealed and protect the bulbs, damage to the housing or seal can allow moisture intrusion, leading to premature bulb failure. Additionally, normal usage, vibration from driving, and the electrical system’s constant stress gradually wear down these bulbs.

Purchasing replacement bulbs

Cars require different bulbs for the different lights around the car. You can find the specific type your car needs in the owner’s manual or online. Many auto part store websites allow you to input your vehicle’s year, make, and model to determine which bulbs are compatible with your car. Remember that with headlights, taillights or other vehicle lights that exist in pairs, it’s best to replace both simultaneously because if one goes out, the chance that the other one will probably also go out soon thereafter is high.

Replacing headlight bulbs

Locate the bulbs

Turn off the car and put on nitrile gloves before handling any working light bulbs.

In the engine bay, locate your headlight housing. Inside the housing, which may require you to unlatch or unscrew an access panel, you’ll find the headlight and front turn signal bulbs.
