Had the usual cloudy headlights on my 2011 Speed Triple Triumph wouldnt replace them so I was just living with them Read a post somewhere on a US forum about cleaning the lens inside Removed headlights, bulb out, sprayed in some isopropyl cleaner, poked a rag in and wiped it around the inside with a piece of plastic, hey presto RH light looks like new, LH one miles better but a bit hazy so will give it another clean tomorrow If I can be arsed to walk to my bike in my lunch break I'll take a pic and post it here....
