Headlights Importance

A headlight restoration service or headlight replacement might be exactly what you need. You may be surprised to learn that 40 percent of traffic fatalities in New England take place at night even though there’s 60 percent less traffic. This exemplifies how important proper visibility is to nighttime driving in Maine and New Hampshire.

Obviously, a clean windshield is important – so are good wiper blades. Your headlights play a big role as well. There are two main concerns. One is with the headlamp, or bulb. The other is with the lens.

The fact of the matter is that headlamps go dim or burnout over time on your vehicle. You just need to replace them. Some vehicles come with a standard bulb which you can replace or you can upgrade to a halogen bulb that’s much brighter. Halogen costs a little more but you’d be amazed at the difference. New LED’s are becoming more available for many vehicles on the road.

When Should I Replace my Headlamps?

It’s a good idea to replace your headlamps once a year. The idea is that your lamps never dim to the point that they become a safety issue. Just take care of it at a your annual Maine or New Hampshire State safety inspection so that your lights will be bright for those hot summer nights as well as for those long winter nights.

The other big issue is the headlamp lens. For the last couple of decades, most lenses are made of plastic which can get cloudy or yellow. That blocks a lot of light. You can replace the lens, but each lens assembly can cost on average between $350 and $400 with some well over $1000! It’s much less expensive to restore the lens if it isn’t broken.

We use a special 3 step process of special cleaners and polishes to remove the yellowed and hazy layer of the lens. We then apply a hard protective finish. When we’re done, your lenses really are as good as new.

The price depends on the size of the lens and how yellowed or cloudy it is. You can even restore taillights and turn signals.

So combining a headlamp restoration with new bulbs will light up the road like a new car. Can you clearly see the advantage?

DID YOU KNOW?

A recent study showed that 9 out of 10 vehicles have dirty or yellowed headlights. This can decrease nighttime visibility by as much as 90 percent. When you gas up, wipe down your headlights to keep them clean. A headlamp restoration can economically clear up cloudy or yellowed headlight lenses.

Frequently Asked Questions

Why do my headlights turn yellow and cloudy?

The polycarbonate lens has a factory UV-protective coating. Over years of sun exposure that coating breaks down, and the plastic underneath oxidizes — turning yellow, hazy, and rough. The haze scatters light rather than projecting it forward, which can cut your effective light output substantially.

Does headlight restoration actually work?

Yes, when done properly. A real restoration means wet-sanding away the oxidized layer through progressively finer grits, polishing the lens clear, and — critically — applying a new UV-protective sealant. Skipping that last step is why cheap restorations look great for three months and then cloud right back over.

Should I replace both headlight bulbs at once?

We recommend it. Bulbs dim gradually as they age, so when one fails the other is usually near the end of its life too. Replacing both at once gives you even, matched light output and saves you a second visit.

Can I upgrade to LED or HID bulbs?

It depends on the vehicle. Dropping an LED bulb into a housing designed for a halogen reflector typically scatters light badly — it blinds oncoming drivers while actually giving you less usable light on the road, and it may not be street legal. If your vehicle has projector housings designed for it, an upgrade can work well. Ask us and we will tell you honestly whether it makes sense for your car.

Will foggy headlights fail my state inspection?

They can. Both New Hampshire and Maine inspections evaluate lighting, and headlights that are severely hazed, discolored, or have inadequate output are a failure item. Restoration is usually a quick and inexpensive fix.

Why is there water inside my headlight?

A headlight housing is vented to equalize pressure, so a small amount of condensation that clears when the lights run is normal. Standing water, or fog that never clears, means the seal or housing is cracked and it needs to be addressed — trapped moisture corrodes the reflector and destroys bulbs.

Signs you need this service:

  • Headlight is out or noticeably dimmer than the other side
  • Cloudy, yellowed, hazy, or oxidized headlight lenses
  • Flickering or intermittent headlights
  • Poor visibility at night or in rain and fog
  • Headlights aimed too low, too high, or off to one side
  • Failed state inspection for lighting
  • Moisture or condensation inside the headlight housing
  • High beams work but low beams do not (or vice versa)

Our process:

  • Confirm which bulb or circuit has failed and test the electrical supply
  • Inspect the housing, connector, and wiring for corrosion or heat damage
  • Assess lens condition for oxidation and hazing
  • Recommend bulb replacement, lens restoration, or full assembly replacement
  • Replace bulbs in pairs so both sides match in brightness and color
  • Perform multi-stage lens restoration — sanding, polishing, and UV-protective sealing
  • Aim the headlights to the manufacturer's specification
  • Verify low beams, high beams, and daytime running lights all function
  • Check that the lights meet state inspection requirements
