If it's a staggered bayonet pin, that implies that it is a dual 'filament' bulb to be used with a changeover switch.There is no flat. As I said it is cylindrical. The only clue is that the bayonet pins are at different heights.
Is it a single central contact like an old winker bulb, or two contacts like a brake/tail bulb or mains bulb?None of these are anything like mine. It is a silver coloured cylinder 50mm tall plus the small diameter bayonet. It has 12 vertical rows of 5 LEDs.
