No driver wants to be dazzled by oncoming headlights when they’re on the road. Adjusting the vehicle’s headlights correctly should prevent this from happening, but in case you need a refresher, we’re here to help. 

Learn how to check headlight adjustment with this handy how-to guide from the technicians at Delphi. We’ll take you through the process and answer some questions such as:

  • Why headlights need to be aligned in a certain way for safety reasons

How do you manually align headlights? 

Depending on the vehicle, there will be different ways to adjust the headlights.  Some vehicles require manual adjustment using the adjustment screws for both horizontal and vertical. 

Other cars require the additional use of a diagnostic tool, to first place the headlights in an adjustment or calibration mode.

Is headlight alignment part of the UK MOT? 

Yes, headlight alignment is one of the checks that technicians make on cars as part of their MOT. During the MoT, the headlights will be checked for vertical and horizonal alignment, and checked to ensure that both headlights have the same brightness and color output. 

How long does headlight alignment take? 

The time it takes to perform a headlight alignment depends on a number of factors such as what make and model of car you’re working with – there may be different ways to move the headlights around, and some are easier than others.

    Cabin Air Filters

    The cabin air filter is responsible for cleaning outside air entering the vehicle. Because up to 100,000 litres of air can be blown into the vehicle’s interior in less than an hour, it can easily become clogged with debris. Unfortunately, a blocked cabin filter will not be effective, resulting in a below-par heating and cooling system, and causing the air inside the vehicle to become more polluted than the air outside up to six times more. Similarly, bacteria and fungi can accumulate in the filter, leading to unpleasant smells in the cabin. Fitting a high-performance cabin filter, such as Delphi, is essential in eliminating these harmful pollutants and odours, safeguarding both you and the air conditioning (A/C) system.
