Hi, Had these on my bay, but am going to a more old school look, so sticking my original ones one. The light beam is improved with these, so the box says, takes a H4 halogen. The glass is slightly cloudy, needs a clean with a stick and a rag inside, or just use as is. I did. Would look cool with yellow bulbs Same as these at £72 quid: http://www.vwheritage.com/vw_spares_Headlamp-Euro-look-Clear-pair-AC941103B_act_shop.product_pID_157042_lang_EN_country_GB.htm?crumbStartPage=1 Will post for a few quid. Cheers. Alistair
