Dim Headlights

When your vehicle’s headlights start to go dim, it’s usually a sign that they’re beginning to die. Typically, dim headlights are caused by the bulbs reaching the end of their life, and they need to be replaced by a new set of bulbs. This is the most common type of headlight issue that drivers will encounter. However, drivers should take care to get their vehicle in for a bulb replacement in a timely manner, as poor illumination can be a significant safety hazard in poor-visibility conditions.

Flickering Headlights 

If a vehicle’s headlights begin to flicker, it’s possible that the bulb filaments have become damaged, or have significantly worn down. Flickering tends not to last too long, as the bulb or bulbs that are flickering will usually burn out completely in a short period of time. Flickering can also be caused by a loose connection, which can be easily repaired. 

Headlights Won’t Turn On

Headlights that won’t turn on at all can be the result of any number of issues. While this may be due to the headlight bulbs reaching the end of their lifespan, they’ll typically go dim before burning out completely. This issue could be the result of a faulty set of bulbs, or may be a symptom pointing to a larger electrical issue. Typically, if a vehicle’s electrical system is experiencing issues, the headlights won’t be the only lights on the vehicle with issues. Drivers should check their dashboard lights, taillights, and cabin light to see if they are experiencing problems as well.
