996 Rear Fog Lights

[Fairfax]

OK gang, rookie question for the experts. Working through the tail lights on my recently purchased 99 996 Cab and all the bulbs seem to be working now after replacing a couple and finding one socket empty. But when I activate the rear fog light only the driver side illuminates.
I seem to remember back years ago a European fog light hanging below the bumper on the rear of several models. But I cannot confirm in my owners manual that is is only a light that functions on one side.
Can anyone shed some light on this?? thanks in advance for your input!!

I have a 99 996 Coupe and same thing - only driver's side rear fog lamp lights. My friend has an 05 997 Carrera S with the same left-only fog lamp. Curious! My Bentley manual wiring diagram shows both lamps wired to the headlight switch directly - two separate wires but nothing in-between lamps and switch.

Driver side rear fog light is standard. Supposed to make sure vehicle behind you sees your car but doesn't mistake it for brake lights.

Thanks for your response, makes sense to me.
