What are the different types of car lights?

Despite the diversity of the market, many carmakers continue to rely on more traditional technologies. In fact, the last few years have seen the emergence of cutting-edge technology in car lighting, mainly around the development of light-emitting diode bulbs or xenon LEDs, in which a gas as a light source. But these technologies are expensive. In addition, conventional light bulbs, called incandescent or halogen bulbs, continue to equip the vast majority of entry or mid-range models.

The halogen bulb has a design similar to the conventional incandescent bulb. Both are part of the so-called heat-radiating bodies, that is, capable of transforming the received electrical energy into heat which, in turn, emits light radiation. Both consist of a gas-filled vacuum bulb containing a tungsten filament. The difference in the case of halogen bulbs lies in the addition of halogen gas atoms (iodine or bromine) to this atmosphere, which allow to reach a higher temperature, and therefore a better brightness. Due to their anti-blackening properties, halogen bulbs also have a longer service life.

How to replace a broken light bulb?

If a light bulb burns out and no longer provides the expected light, you can try replacing it yourself. To do this, just follow a few simple steps as described below. Please note, however, that the process may vary depending on the year, make, and model of your car. Also, be sure to always consult your vehicle’s service manual. We will start with the headlights.

  1. Select the headlight you need

You can identify the type of light bulb you need in your service manual. He will give you the exact specifications. Once you find it, make sure you choose a quality brand.

  1. Locate the bulb installation seat

Make sure your car’s lights are off. Then open the hood and locate the back of the headlight. It can be accessed from the inside, at the front of the engine compartment, to the extension of the headlight location.

  1. Remove the back of the headlight

You should see a few wires, usually 3, connected to the bulb socket. Depending on your vehicle, these are held in place by a clip, clamp, or screw. You will need to pull, push, or unscrew these items, that is, all the wires connected to them, in order to remove the bulb from its socket.

Depending on your car, you may need to remove the entire headlight assembly. Consult the owner’s manual if you are unsure.

  1. Installation of the new light bulb

Be sure to wear gloves to prevent skin contact with the new bulb; grease should be avoided at all costs, as this may affect the life of the bulb. Also, never touch the light bulb with your bare fingers. Then place your new light bulb in the headlight compartment and press or attach it.

  1. Replacing the rear bulbs

Access to the rear lights is logically done through the trunk of the vehicle. In most cars, the brake light screw is located behind the light. However, you can find it under the edge of the trunk carpet, or even outside it. Then proceed as described above.

  1. Check your headlight

Turn on the car to check that the new headlights are working. If so, you’re ready to go!

Note: In the case of xenon headlights, seek the assistance of a professional installer, as these operate at high voltage, which can make their installation dangerous.

Most current vehicles are equipped with conventional light bulbs, which wear out over time. Its replacement is not very complicated and anyone can do it. If you notice that one of your headlights is showing signs of weakness, or has even abandoned the ghost, please refer to the instructions in this article and replace it. Don’t wait, because only a perfectly lit vehicle allows you to be perfectly visible on the road in all conditions!
