With the days being shorter now, I need a little extra light. The Dynohub and vintage lamps work fine when there is still some daylight, but when it's truly getting dark, a modern LED is the way to go. The 1974 Raleigh Sports could well use the extra light.
I picked up a CREE LED that comes in a polished aluminum shell, and it really does a nice job. It has a rechargeable battery and even green indicators to tell me how much charge the battery has.
It has 3 beam settings and fits right on the handlebars with a rubber strap. It is completely removable and can work on any of my bikes.
