Question 1

What do headlight bulbs do?

Accepted Answer

Headlight bulbs are responsible for illuminating your vehicle’s headlights. Your headlights, located on the front of your car, are designed to give you maximum visibility while driving. They light the road in front of you at night, and can be used to improve visibility during adverse weather conditions. Just as importantly, headlights make your vehicle visible to oncoming traffic, making them a vital safety feature that must be properly maintained.
