Can anyone recommend hi-viz neon yellow reflective strips for my helmet?

Looking to put some on my black Giro Xen, an otherwise great helmet except that you can only see the Giro reflective letters at night (my helmet is black).

I have the reflective tape that semis use. I bought it from an automotive store for $1/foot and it's far more visable than anything I've seen marketted at cyclists. It's wrapped around my chainstays, seatstays, fork, top tube, down tube, seat post, and helmet.

I picked up some bright yellow stripes/stickers at REI a couple of years ago.

I have some of these: http://www.teamestrogen.com/products.asp?pID=27711 They are good high visibility colors and they reflect well.
