The extra light in the evening allows me to ride after work again. This is always a good sign, because it means I can ride during the week. It helps having a good light, and this particular headlight I made by putting the guts of a 1,200 lumen LED bicycle light into a vintage, Miller shell.
It offers 3 beam levels, plus a hazard flasher mode. The battery recharges, and the battery holder straps right onto the Raleigh's lamp bracket. I'm glad I added it.
