What is a headlamp assembly and what purpose does this serve your truck? A headlamp is also called your headlights. The headlights are the lights found in front of your vehicle. These lights are made brighter and their purposely-directed beams are created with the help of reflectors and lenses that are designed to help you see the road better at night. The term "assembly" means parts that fit together and form what may be called a self-contained unit that works as one. This then implies that a headlamp assembly or a headlight assembly is the self-contained unit that contains the headlights and other parts needed to make this truck part work.

Why Headlight Assemblies Are Important

Keeping your headlight assemblies in top form is important simply because it is one feature of your truck that will help you see the road better at night. While some people say that most roads are lit well enough for them to not need headlights and headlight assembly that function really well, it is actually very important that you have headlights and headlight assembly that work perfectly. Having perfectly working headlights and headlight assembly can save you from potential dangers on dark roads.

Headlight and Headlight Assembly Basics

Headlight or headlamp assembly usually emits two types of headlight beams, the low beam and the high beam. When you use the low beam of your truck's headlight assembly, you basically give yourself enough illumination without giving oncoming traffic glare from your lights. The high beam function of your headlight assembly is often used when there are no oncoming vehicles and you want maximum illumination on the road. These high beam lights are also ideal for those times when visibility is poor, like in heavy rain, or on foggy days. Knowing when to use these two headlight beam types can help keep you safe on the road as well as keep others that you encounter on the road safe as well.

Changing Headlights in Headlamp Assemblies

While most headlights and headlamp assembly can last for at least a year or more without requiring that these be changed, there are instances when these can fail even before you expect it. Once this happens, you will need to change the headlight assembly and lights immediately before you use your truck again to avoid the possibility of accidents on the road. You can actually change your headlamp lights and headlight assembly yourself and all you will need is the replacement headlight assembly for your truck and a screwdriver. Here are some of the simple steps you can follow to do this:

• Open the hood of your truck to locate the headlamp assembly, which is found at the back of the headlight. Some trucks may have a protective cover at the back of your headlight assembly, so you may need to remove this first before you can access what you need to replace.
• Find the headlamp module and turn it counterclockwise to loosen it and remove it from the entire fixture.
  
• You will then need to take out the broken bulb from this assembly, replace it with an appropriate bulb, and return the headlight assembly to how it was by reversing the order of how you removed the bulb.
