Not exactly old school , but I use a pair of the PIAA 520 85w Ion Crystal fogs on the Cruiser - those things are awesome in bad weather be it rain /fog/snow ....
I loved the look of the old Cibie lamps , but trying to find a good set is nearly impossible . I'd really like to find a pair of the H4 headlight lenses w/city bulbs , at least for less money than the current vendors get for them .
