Apologies if it’s already been done, about to start night riding…quite happy with my magicshine lights but could do with something else on my lid. Any cheapies out there, it’s a minefield on evilbay IMO lol… Ta

I recently got a BT21 from Gearbest for £40 works well as a helmet light.

I use a cheap and abundant Chinese Ultrafire light on all three of my bikes. Works well after doing the slight mods shown here – https://www.youtube.com/watch?v=zJpQAvum0bM

The brackets (though clunky looking) work well on handlebars but don’t work on helmets. If you can find a helmet bracket that takes a light with an external diameter of 25mm then that should work.

+1 for Gearbest, they do a Yinding cree light, good battery life and just like a glowworm.
