This lamp unit looks like it is from a Rover 200.
As well as being fitted to various 200 derivatives (inc. the 200 Coupe and 400 Saloon) the light was also used in the diesel-powered Honda Civic 5-door that was sold on the French market (basically a Rover 200 with Honda badges to satisfy the high demand for a diesel Honda in France at the time). Apart from that though, I can't think of any other cars using this unit.
