Is a headlamp patented?

Short answer: specific designs of a headlamp have been patented many times, but "a headlamp" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a headlamp been patented?” but “has my combination of features been described before?” Outdoor products differ mostly in weatherproofing, power source, folding mechanisms and how they mount or anchor.
