Jetta CLi's (South Africa only?) used the same headlight housing as the Rallye. So it makes sense that a VW parts joint in SA would have both OG Hellas and cheap knockoffs.
Some guy from SA was on here years ago selling the housings - Rallye-Tecnik, something like that. IIRC Mason got a couple sets, and said the quality of the knockoffs was okay, but shipping costs and export / import duties made the deal not worth fooling with.
My guess is the knockoffs are or were the lights InPro was hyping to US distributors a few years ago.
