A lot being said about the possible 'bite light' in lantana mans mouth and so I wanted to post up a run down of the most likely people to have such a light handy.
Common user profiles include:
Pilots (especially general aviation and night flyers) — They use models like the Flight Gear Bite Light with white light for pre/post-flight checks and red light to preserve night vision in the cockpit.
Theater technicians, lighting crew, stagehands, and wardrobe personnel — In tech theater and backstage work, bite lights (often called "bitelites") are popular for climbing ladders, focusing lights, quick changes in dark wings, or when carrying gear.
Mechanics, auto technicians, or anyone working under vehicles/dashboards — Hands are occupied with tools, so mouth-held light helps see tight spaces.
Performers or quick-change artists (sometimes in drag, costume, or low-light creative work) — Soft, teeth-friendly versions exist for hands-free illumination during fast changes or detailed work.
Jewellers and Crafting Hobbyists — Anyone who works regularly with crafts that require both hands to be free during intricate work.
DIYers, electricians, plumbers, or home repair folks — Anyone who's ever held a regular flashlight in their mouth under a sink or in an attic ends up appreciating a purpose-built bite version.
Outdoor/night workers — Like some night fishing setups (though "bite light" there more often means bite indicators/alarms), or cavers/explorers who prefer mouth-held options over headlamps in tight spots.
