Sprint 2009 St 1050 Rear Light Same As 2009 Tiger

Need a new rear light for my Sprint as vibration has caused the brass lugs to work loose and crack the plastic. Have done a temporary repair with plastic filler and epoxy but have seen a good used Tiger one for sale at a non silly price. Triumphworld / Fowlers images look same but give a different part numbers, just wondering if this is a sales ploy, in any case the ST is out of stock. Thanks
