I have both reflective gear and lights on my bike and helmet. I've had bus drivers who have commented on seeing my lights when I was out after dark and watching for a bus coming behind me so I could pull over. The light set is made so you can wear them on wrists or in this case, I ran the straps through my helmet vents pointing the white forward and the red to the rear. I usually put them on blinking then my headlight on the bike steady. Sometimes my bike tail light is solid, but more often it's set to blink as well.

I also wear ankle biter reflective straps one on my wrist and one on my ankle on my left side facing traffic.

When I'm using my new kitty litter bucket panniers, I have a large red reflecter on the backs and amber on sides and fronts. I plan on adding reflective sewn on tape to the sides of my tights that I've made for colder weather riding and more reflective material to my helmet. I've never been worried about looking like a dork as long as I'm seen.
