The history of car headlights

Car headlights were invented in the late 19th century, just as cars were gaining popularity. Early models were powered by acetylene gas and required manual ignition. It wasn't until the 1920s that electric headlights were introduced, offering greater efficiency and safety. Modern headlights offer advanced technologies such as LEDs, xenon, and lasers, providing improved visibility and energy savings.

Types of car bulbs

Halogen

The most popular and relatively inexpensive. They are characterized by good performance but a shorter lifespan compared to other technologies.

LED

They offer longer lifespan and better energy efficiency. They are more expensive, but their durability makes them a cost-effective choice.

Xenon

They emit very bright light and have a longer lifespan than halogen bulbs. However, they require special ignition systems.

Preparing to replace a light bulb

Before replacing a bulb, make sure you have the correct tools and a bulb that fits your car model. It's also important to turn off the car and allow the headlights to cool down.

Necessary tools

• Screwdriver

• Protective gloves

• Car owner's manual

Security

Always make sure your car is parked on a level surface and the handbrake is applied. Turn off the engine and wait a few minutes for the headlights to cool.

Step by Step: How to Change a Light Bulb

Opening the hood

Locate the hood release lever in the cabin. Once the hood is open, secure it with the hood stays.

Headlight housing location

Locate the rear panel of the headlight where the bulb is located. You may need to remove the protective cover.

Removing the old bulb

Unscrew or unclip the access panel. Gently remove the old bulb by grasping its base.

Inserting a new bulb

Install the new bulb, avoiding touching the glass. Reinstall it in the same spot where you removed the old one.

Closing the housing

Close the access panel and make sure everything is securely fastened. Close the hood.

Test

Turn on the headlights to make sure the new bulb is working properly.
