Just as slowly deteriorating vision could go unnoticed, the same is true with your vehicle’s headlights when the bulbs dim with age. Molly and I don’t have this problemas our sense of smell can compensate for vision and hearing issues. Your car, of course, doesn’t have that option.
So, if your headlights aren’t as bright as they used to be, call the shop for an appointment to check whether they should be replaced or restored. With age the plastic on your headlights can become clouded and reduce the amount of light they emit creating poor visibility. In the picture the right side is a restored headlight and the left side is an aged one.
Keep your windshield clean too, inside and out, and make sure you have good wiper blades and plenty of washer fluid.
Your safety depends on good visibility. Stay safe.
