I have a copy of the 'Bishi parts list for the front 5 fog.
Fog lamp glass does not appear to be listed as a separate part;
you need the whole unit, part number 80249L (left) or 82049R (right).
If your sitting comfotably ill tell you the retail price....over £360|PLS|v for the pair !!!
I am about to order a pair for my 5, I only need drivers side....so if you want a passenger
side....this may be your lucky day !
