Treat Your Eyes To Cleaner, Brighter Headlights

Just like prescription glasses hone your vision, a pair of clear, bright headlights will sharpen your visibility and improve your view of the road.

Headlight bulbs can dim over time as the bulb ages. There’s also instances where the bulb itself is fine, but the headlight’s plastic case is hazy. Cloudiness reduces and diffuses the amount of light going through the lenses, meaning less visibility when it’s dark.

But why do headlight cases get cloudy? The simple answer is oxidation.

Years of intense ultraviolet rays from the sun can degrade the polycarbonate or plastic housing the headlight. Over time, pockmarks and imperfections in the casing oxidize and become cloudy.

This haze can sometimes be removed at home or by a professional. Ask your service advisor or trusted car care expert about headlight restoration kits.

Below, SYLVANIA Automotive offers some tips and insights about headlight care:

  • Always replace headlights in pairs. A new bulb paired with an old bulb will create an uneven field of vision for drivers, which can be a major distraction for both you and other drivers.
  • Consider cost, lifespan. High-performance Halogen bulbs emit almost as much light as Xenon HID bulbs but have a shorter lifespan. Standard Halogen bulbs are the least expensive bulbs and provide lower light output.
  • Alignment matters. Are your headlights cock-eyed? Ask your service advisor to check direction of the beams and make necessary adjustments.
