How to Repair Car Headlights?

What Causes Car Headlights to Malfunction?

If the headlights of your vehicle are not working, flickering, or have become dim, you either need to fix them yourself or get them repaired by a mechanic. Generally, the following causes are responsible for headlight issues:

Top 5 Ways to Repair Car Headlights

When your car's headlights start to flicker or simply stop working, you must check whether the wiring, batteries, bulbs, and other components are functioning properly. Here are some commonly used ways of repairing a car's headlights:

Replace the Bulbs

Defective or worn-out bulbs are a common cause of headlight issues. You can have the bulbs replaced at a garage or do it yourself at home. Here's the step-by-step process:

• Step 1: Open the car's bonnet. Make sure the car is parked and the engine is off.
• Step 2: Use the vehicle's manual to locate the headlight assembly.
• Step 3: Remove the existing bulb by twisting and pulling it.
• Step 4: Install the new bulb and connect it to the wiring.

Repair or Replace the Wiring

If replacing the bulbs has not fixed the problem, the flickering or non-functioning headlights may be caused by loose or defective wiring. If you have basic technical knowledge, here is how you can fix this issue:

• Step 1: Take a multimeter and set it to voltage mode.
• Step 2: Check if power is reaching the headlight's socket.
• Step 3: If there is no power, inspect the wiring for any breaks or damage. Repair or replace damaged wires and secure any loose connections.
• Step 4: Clean and tighten the ground connection near the headlights to eliminate grounding issues.

Fix Battery Issues

Battery problems can also cause headlights to flicker or get dimmer, especially when accelerating or driving over bumps. Here are some steps you can take to resolve these issues:

• Check whether the wiring of the car's battery terminal is loose. If they are loose, tighten the clamps.
• See if the battery is corroded due to moisture or acid leakage. Clean the battery terminal with a brush and apply a coat of petroleum jelly to prevent this issue.
• Test whether the battery is weak, old, or worn out using a voltmeter. You can get the battery replaced to solve headlight issues.

Clean the Headlight

The headlights of your car can become yellow or cloudy due to wear and tear, weather conditions, and dirty roads. Here are some helpful methods to clean them:

• Carefully clean the headlights with wet sandpaper, then wipe them with a towel.
• You can also use DIY headlight restoration kits. These kits typically include sandpapers, abrasive discs, foam discs, and restoring compounds.
• Alternatively, you can get your headlamps cleaned by a professional.

Realign the Headlights

If your headlights are working but not illuminating the road properly, they may be misaligned. You can correct their position using the following method:

• Step 1: Position your car on an even surface in front of a wall. Park it around 25 feet away from the wall.
• Step 2: Turn on the headlamps and mark the beam's current position with tape.
• Step 3: Use the headlight adjustment screws on the back of the headlight housing to adjust the headlight position.

Does Car Insurance Cover Damage to the Car's Headlights?

Whether car insurance covers damage to your car's headlights depends on the cause of the damage. If the incident is covered under your policy, you can claim compensation for the repair or replacement of the headlights.

A comprehensive car insurance policy typically covers headlight damage caused by accidents, collisions, natural disasters (such as earthquakes, floods, cyclones, and hailstorms), fire, and man-made events (such as vandalism, riots, strikes, or terrorist activities). However, damage will not be covered if it results from normal wear and tear, electrical or mechanical failure, incidents occurring outside India, intentional damage, illegal activities, or other policy exclusions.

Should You File a Claim Under Car Insurance for Headlight Repairs?

It might not always be the best idea to file an insurance claim if the headlight issue can be fixed at home or at a garage for a minimal cost. Filing a claim could cause you to lose your No Claim Bonus (NCB), which is a discount on your premium for staying claim-free.

Additionally, if the repair cost is lower than the deductible, the insurer will not provide compensation, rendering the claim unnecessary.
