Sadly, a majority of drivers forget to use all their car light correctly as soon as they pass the driver’s test, putting their lives and those of other motorists in danger. Various car lights have specific functions to give the driver better visibility or to signal other road users.

When not used properly, or not used at all, an accident may occur. Thus, ahead of your headlight restoration schedule in Arizona, here is a breakdown of various types of vehicle lights’ and when to use them.


This is the most popular yet the most misused. They are available in two categories; that is, high beam and low beam headlights. High beam lights have a center-weighted and intense light distribution with no glare control.

Thus, they should only be used when there are no visible vehicles ahead of you, both going or on coming. Low beam, on the other hand, distribute light to give an oblique and forward illumination to you, without blinding other drivers on the road with excessive glare.

Hazard Lights

Also referred to as flashers, these lights are on both the back and front of the vehicle. By turning them on, you are notifying other road users that you are in distress, you are having a problem, or you are warning them of immediate danger. Note that they should never be used as a stop signal, a traffic signal, or illegal parking signal.

Fog Lights

Car owners place these lights near the headlights and mount them lower than the headlights. This is in a bid to prevent the light bulbs from refracting on the present fog, causing a glaring effect back toward the driver. Fog lights are to be used only when there is fog as the ordinary headlights will not be effective.

It is well worth it to familiarize yourself with car lights and understand what goes where. Note that the malfunctioning of one type of headlight could result in accidents. As such, do not substitute one light with another as each serves a purpose.
