New Life for Old Headlights

If your plastic headlight lenses are looking hazy like mine were, you can probably recondition them so they look near-new for about $15 and 30 minutes of time.  I used the 3M Headlight Lens Restoration System, which comes with 500 grit and 800 grit sandpaper, a 3000 grit wet sanding pad, rubbing compound, a foam polishing pad, and an attachment for your drill.  It takes a little patience to go through the steps of sanding and then finally polishing it all out, but the results are great.  (In the picture below, the top units are reconditioned and the bottom units are not done yet)
