I have a decent light with a remote battery and a couple of ebay cheapo specials. I use the good light as a head torch for proper night rides and the torches for the commute.
What I want is a good floody torch to go on my bonce to allow me to go fast offroad for those times I get a cheeky extended commute.
I don't want to use my good floody light on the bars as I like to see where I'm going.
What are my options? Cheap preferred but not essential. Run time doesn't have to be massive.
