Yep, If you decide to produce the screw in type (PR22?) I have a couple of magnifyers and an old aluminum Justrite "penlight style pilots" I bought at an Army-Navy store 40+ years ago I'd upgrade. If you don't go into production, I'd like a prototype if one is available. Shamefully, in my youth, I abused the pilot light by removing the hood that held green and red plastic strips that changed the lights color and cut the tip off the pocket clip because it caught on my jeans pocket. (Flashaholic even then) But the old light deserves a chance to shine again!
