Chaps Halfords do these blue tinted headlights for our zeds.

 

What do we think?

Regardless of colour they will still be dim!!

I tried them for the Dipped beam a few years ago and couldn't see a bloody thing in the rain, although they claimed to improve rain vision. I reckon they conflicted with the projector lense. They may be alright for main beam (I never tried).

 

PS - Took them back to Halfords and no problem with refunded.

It's Christmas soon, so there will be lots of Quality Street wrappers knocking around. They come in lots of colours so you have a much wider choice. Of course they will melt eventually if you put them over the bulb, but then that's a good excuse to eat MORE chocolate!:D :D
