The 3M 39084 Headlight Restoration Kit is down to $8.91 on Amazon if you choose the Subscribe & Save option. This is a feature that will send you the product on a regular interval unless you cancel it (and there's no penalty for doing so). Even as a one-time purchase it's only $10.48, which is still a great price considering it normally sells around $15 or more.

Have a hard time piercing the darkness with your old headlights? Maybe you don't need to replace the lights themselves. Maybe the cover just needs some polishing and cleaning to get rid of the built-up dirt, haze, and yellowing. This kit has sanding discs and polishing pads along with a compound to help them look like new again. You can use it on headlights, taillights, fog lights, and directional lights. If it doesn't make a huge improvement, maybe you replace the lights, but if it does work you've spent $10 and saved yourself a ton of money. Users give it 4.5 stars based on 7,229 reviews.
