Is this reflective enough for you?

Could be a repost....

Actually, no it isn't :D I used Reflexite V82, which is very high-performance prismatic tape. Comparing even the silver Scotchlite to Reflexite V82 is... well, 1000 words on the subject:

The dimmer patches of tape on the rims are silver Scotchlite, the rest is V82. I seem to recall that the black Scotchlite is at least an order of magnitude less reflective than the silver.

But I give him an A for effort :)

These are cool, but I'm a bit scared of putting real tape all over my bike, so I use a temporary product that is also extremely reflective.

IMHO, it's also really important to combine reflective surfaces with active lighting and high-vis colors that are visible in the day (black tape doesn't quite have that quality).

I agree. I've seen motorists driving with their lights off until nearly dark, and even AFTER dark, so no light = no reflection. And then there's cross-traffic whose lights are aimed elsewhere, etc etc. There are plenty of daytime-visible front and rear lights, and I usually wear a yellow or neon-lime outer layer in the daytime. In twilight and darkness, I also run a yellow BikeBrightz on the bike in the photo, and a yellow FibreFlare on my other commuter, for active side lighting.

That bike also has a relatively subtle dose of Reflexite V82, which looks like this with/without camera flash:

Why am I hearing that Verizon ad guy in my head? Only this time he's saying "Can you see me now?"
