The manufacturer tag on this one says Girling, but Girling made brakes and dampers, not lighting equipment, so that tag doesn't hold up against what the part actually is. This is a lighting assembly, and it lives up front on the bike where the speedo and tach mount alongside it, based on the figure groupings it appears in.
Our catalog data only shows this appearing in 1971 listings, and it shows up twice across the figures we have. If you're trying to match this to a specific model or year beyond what's shown here, give us a call and we'll confirm fitment before you order.
