if you're worried about seeing the road in front of you, you really don't have any other options than a 20+ dollar battery powered system that sucks and is only good for being seen by, or a 80+ rechargable halogen lighting system that actually works. expect to pay 120 for one that will make you happy.

if you're worried about being seen, buy some 10-20 blinkie lights along with some reflective stuff and blink the **** out of others. they work fine, especially for cars that will light up your reflector stickers/vest/cuffs/tape.
