One that looks more like a reflector, unlike the EVO-R LED lit one, is the JDM/Euro Rear Foglight:
Motorsport! European Rear Fog Lamp, 09-12 370Z - The Z Store! Nissan-Datsun 240Z-260Z-280Z-280ZX-300ZX(Z31/Z32)-350Z-370Z Parts
It is lit by a single bulb. While turned off, you could say it looks close to a reflector, no?
