Neil,
Hey Cuz! Here is what a 1992-3 124 looks like with 1994-5 euro lights but with the older hood. I still haven't upgraded my hood yet. I've been driving with the updated lights and original hood for over a year now and no one has said anything. Even when I point it out, it is hard to notice.
It bothers me the way it looks, but the new hood is a few months away still.
Hope this helps!
