Here is a great source for reflective tape of all sorts, including SOLAS.

I have purchased from them, sevice and prices are very good. The red reflective here

lights up very well, and the red matches my vfr well enough that I was able to put it directly on the bodywork in key places but it is undetectable in daylight.
Forward fog lights, yellow especially seem to work. For style point I recommend motolights.

Very functional and well made, but not DOT approved. As if I care. I had a pair on my VFR, but they were trashed in an accident.
Because of the price I went cheaper on the replacement and got the electrical connection lights with specific fitting kits for my VFR. They were much cheaper and I got what I paid for in product and service. 3 months and multiple phone calls to get them to ship. After a few weeks using them I threw out the
[email protected] lights and got a pair of PIAA's off ebay which have worked out very well.
If you get a set of Givi's, get the optional brake light for the top bag. Double the brake light doesn't hurt.
