Lincoln Town Car Headlight: Cleaning and Restoration

Keep your headlights bright. One way to do this is by making sure that the headlight lenses aren’t dirty and foggy. If they appear dull, yellow, or grimy, all you have to do is clean them up and polish them. We have some tips for cleaning and restoration for a Lincoln Town Car headlight set. Here are some of them:

Cleaning the headlights

  • Wash the headlight lenses using car soap or some dish detergent.
  • Clean and rinse the headlight lenses with lukewarm water.
  • Use a lint-free cloth for wiping the headlights dry.
  • Make sure that the headlights are completely dry before you polish them.
  • Polish the headlights by applying some buffing compound with a clean micro-fiber cloth.
  • Buff the headlights until they’re clear and shiny.

NOTE: To keep the headlights in better working condition, you may apply some plastic adhesion promoter on the headlights, add some layers of automotive clear coat, or wax the headlights.

Fixing foggy headlights

  • Use a damp cloth for rubbing toothpaste onto the headlight surface.
  • Rub the headlight surface until the haze or oxidized plastic is already cleared.
  • Be sure to rinse the headlight surface thoroughly to remove any toothpaste residue.
Headlight cleaner
  • Apply the cleaning solution on the headlights using some soft scrubbing pad or sponge.
  • Scrub the cover in circular motions, covering all corners.
  • Allow the solution to sit for no less than 2 minutes.
  • Clean off the cleaner on the headlight cover using some dry, clean cloth or towel.
  • Remove the residue using a damp, clean cloth and dry it with a towel or rag.
  • Wet the sandpaper that will be used to fix the foggy surface.
  • Sand the headlight surface up and down, starting at one side and onto the other.
  • Apply some rubbing compound on the headlight surface using a clean cloth.
  • Buff the headlights until they’re shiny using a clean, lint-free cloth or an electric buffer.

NOTE: You may wrap a sheet of 500-grit sandpaper around a foam or sponge to easily sand the surface until it’s even and smooth. Wipe it with a microfiber cloth and then move on to sheets of 1,000- and 2,000-grit sandpaper that’s soaked in a mixture of dish detergent and water. Wet the surface from time to time when sanding until the rough spots are cleared. The process should including washing and rinsing before moving on to sanding with another sheet of sandpaper. Once sanding is over, apply some polish on the lenses using some micro-fiber cloth. The headlights should be rinsed thoroughly and allowed to dry completely.

  • Lincoln Town Car Headlight: Problems and Solutions

    Navigating through poorly lit streets or during heavy rains, snow, and fog would be too difficult if your Lincoln Town car headlight is having some troubles of its own. If it’s no longer burning bright, not aimed right, or won’t turn on, then this can make driving unsafe. Don’t take a chance with faulty headlights. Figure out the headlight trouble right away so you can fix it and get back on the road in no time. Here’s a short guide.

    Dim headlights

    Headlights that seem to change their brightness or appear dim may be caused by a problem with the charging system. It may have something to do with a faulty alternator or drive belt. Confirm the charging system problem through the charging voltage when the engine is idling. Consult the manual for the voltage requirements at the battery.

    Headlight beams don’t light up the road properly

    Headlight beams that fail to light up the road well may be caused by a number of factors, including dirt-filled headlights, foggy or discolored lenses and covers, and headlights that are not aimed right. Check the lenses and covers for dirt, moisture, and oxidation. You have to clean them up. In case of moisture, you have to check if the housing is cracked or there’s a broken seal that’s been causing the leak. Check the aim of the headlights and adjust them as needed through the screws or any other mechanism. Read the manual for proper headlight aim.

    One of the headlights won’t light up

    When the headlight won’t light up anymore, this usually means that the bulb has burned out or has reached the end of its service life, which depends on how long it has been used and how much it has been exposed to vibration. You still have to confirm, however, if a burned-out bulb is behind the headlight failure. You have to check the electrical connector first and see if it’s corroded, loose, or damaged in any way. If the bulb turns out to be the culprit, then it must be replaced as soon as possible.

    Both headlights won’t light up

    There are a number of possible reasons why headlights won’t turn on. This can be because of lack of power caused by a faulty relay, bad fuse, defective module, broken switch, or wiring problem. To trace the real source of the problem, you have to take a look at the fuse for the headlight circuit to see if it’s already blown or if there’s a short circuit or some overload. If the fuse turns out fine, you have to check if there’s power getting through by using a test light or voltmeter. There could be some wiring trouble if the test reveals that there’s no power at the fuse. A wiring diagram will help check the circuit to figure out where the problem lies. Once the fuse is fully checked and there seems to be no fault, next on your list should be the relay or control module. For the relay, it has to be disconnected and checked for rattling. If the relay is at fault, this should be changed to make sure that the headlights will be powered up. For the control module, you have to check the wiring, relay, and switch first. If the module appears to be receiving power when the headlights are switched on, then the module may already have gone bad. If there’s no voltage flowing through the relay or module, the switch is usually the problem here. Check if the headlights work properly on both high and low beams. If not, then you may be looking at a bad dimmer switch.
