Just fitted some new lights. They're really good, too good in fact. Dazzling is a bit of a problem, The plan was to dip them right down but they're still too bright for riding lights. Does anyone know of some sort of filter I can put over the top of the lens? They're 55w Halogens so get hot. The lights are housed in an aluminium carrier so I could fabricate a cover fairly easily, just need a filter of some sort.Any suggestions welcome, (other than 'take them off').
