I have a brass and a copper Reylight AA/14500 Pineapple. Carry them both sometimes. A little hefty of course being copper and brass but, damn fine lights to EDC if you want copper or brass. If you can find a Olight S1A in copper. It’s really great as well. S1A can be a bit hard to find at reasonable prices. A WTB might yield you one if you give it a shot.
Those are the only AA/14500 lights I have in copper. Can’t speak for any other lights. I have a Maratac AAA twisty in copper. I believe they make a AA version. Not sure if it supports 14500 either. If the AA one is as good as the AAA one, then it would be a nice choice as well.
