This is a really cool product that I saw recently on BikeHugger:
Glo gloves are simple, reflective over-gloves which will help you survive your night time rides. Here’s a good review by the Gadgeteer, but you won’t need too much convincing once you understand the value of the gloves.
These are the same gloves you see police officers directing traffic with, although there are 3 models, only one of which has the ‘stop sign’ on the palm. You can get this model online or at uniform stores here in Seattle and elsewhere.
The gloves will help you stay visible during one of the riskiest road maneuvers for a cyclist — turning. Signalling is a great way to improve your safety, but if drivers can’t see your signals they don’t count for much. Glo Gloves increase your odds of being seen. At around $20 they’re incredibly cheap insurance.
