The indicator units I got came from an Italian seller that I have bought from before. The last set I got from him came in Bosch boxes, this pair came in plain boxes. I can not see any manufacturers markings on this one I'm looking at now, but to me at least these ones look good quality. I have not got a 'NOS' Fiat one to compare it with, but I'm quite happy with it. One thing is for sure, it is certainly better than the rotten original ones you find on may cars! One reason that things often sell better on ebay in my opinion is that each listing usually has a photo of the item and a price either for bidding which usually starts low and attracts bidders or a definite buy it now price. People do also buy from forums however. I listed my 2 litre twin cam engine on Retro Rides with a description and price and it is now sold and paid for.
