The Museum of Modern Art Store is a glittering beach of industrial design where seaglass gems pile up, exquisite of design and function. A stroboscopic hazard flasher bought there just across from the museum a decade ago served a good 9 years, keeping Kenworths from eating me and my bike in the predawn murk. One drop too many, and it failed, finally. I kept the lenses. Seriously, spend some time at the store, it is the last repository of mass-produced modernist good taste in the U.S.
