If a head lamp is scratched but not broken, what should you do?

When a headlamp is scratched but not broken, the appropriate action is to sand and buff it. This process effectively removes surface scratches and can restore the headlamp's clarity, enhancing both functionality and aesthetic appearance. Sanding involves using fine-grit sandpaper or a similar abrasive to level the area surrounding the scratch, followed by buffing with a polishing compound to achieve a clear finish.

This method is often more cost-effective and environmentally friendly than replacing the headlamp entirely, especially when there is no damage that compromises the integrity of the lamp. Applying a protective coating afterward can help maintain the finish but is secondary to restoring the surface itself. Addressing minor scratches this way helps prevent more significant issues that could arise if the scratches lead to fogging or moisture intrusion.

Therefore, sanding and buffing is the correct approach when dealing with a scratched headlamp that remains functional and intact.
