What You Need To Do In Replacing and Adjusting Halogen and Xenon Headlamos


Before seeking to replace or adjust your headlights. It is possible to tell which kind of headlights you might have by taking a look at them when they’re on at night you need to know whether you have halogen or xenon headlamps or maybe the old-style sealed-beam units.

Headlights with sealed-beam units are quickly heading out of style. The sunshine they give off is just plain white. Many modern vehicles have halogen headlights. The newest models often come with HID (high intensity discharge lamps), otherwise known as xenon or bi-xenon lamps. Light from xenon lamps has a bluish cast.

Even though they are a lot more powerful than sealed-beam units and enable a driver to see 20 % xenon, farther and halogen units require less capability to operate. Xenon are the brightest, have the longest life, and consume the least power. Replaceable lamps that don’t have to be within round or rectangular housings, halogen and xenon headlamps have also allowed designers to obtain pretty creative with shapes because they use small.

To replace a bulb on a halogen or xenon headlamp, turn off the car and follow these steps:


1Open the hood and locate the wiring leading to the electrical connector that plugs into the bulb assembly.

Utilize this figure to assist you find the connector.

2Remove the connector.

The connector might be held in place by a ring that unlocks by twisting it counterclockwise, by a little catch you need to press down while pulling on the plug, or from a metal clip that pulls off (don’t lose it! ).

3Pull the bulb assembly, remove the old bulb, and install the replacement.

Don’t touch the replacement glass bulb! Natural oils through the skin on the fingers develop a hotspot that may cause the new bulb to burn out prematurely. Instead, handle the bulb by its plastic base or maybe the metallic tip, if it has one. Also, these fragile bulbs are filled with gas under pressure, so make sure you avoid breaking them.

4Replace everything, replug the connector, and turn on your headlamps.

If the bulb is still out and the fuse is okay, have a professional diagnose and fix the problem.


If needed, 5Adjust the beam.

It’s most important that they can be properly focused to avoid temporarily blinding other drivers, pedestrians, or animals, because HID headlamps are so intensely bright.

It provides two adjusting screws, as shown here, if you need to adjust the alignment of a halogen headlamp. The screw at the base angles the beam higher or lower; the one at the top or side focuses the beam left or right. The beams should illuminate the stretch of road ahead of you, not the oncoming traffic. If your lighting is really away from whack, have a service station adjust them for you.
