Cateye was the make, I think they have ceased but there may still be some kicking about. 

My theory is that the manufacturers don’t want to insinuate that their auto focus is less than perfect by addition of a simple but effective focus aid which gives a single point of focus rather than a zone of focus based on your focus point. 

After all, they have spent a lot of yen? Perfecting their AF system.
