Having recently applied a few strips of reflective yellow tape onto my panniers - to help increase my visibility to other road users - I thought some of you might be interested in this link. Good range of wider width tapes here. Actually got mine from BikeSeen but would have considered this one had I known about it.
I've used Bikeseen and been happy with the service, but that is a useful addition to the list .
Today's useless item, using reflective tape other than red on the back of a bike is unlawful. Hi viz, non reflecting, yellow on the back of a bike is fine. Any colour reflective on the rider's kit ditto. But only red reflective on the bike. Daft.
