I bought an amber strobe as recommended in this thread but will not be installing it unless I start riding on the streets more. If you look at my switch box you will see that I have three switches which would allow me to install the strobe or a third light with a helmet mount without much hassle. About the strobe, I have tested it and can tell you that there is no way for a normal blinkie to be that bright and annoying so go for it if you need a taillight. Before deciding on that handlebar bag from Walmart I tried a frame bag and a trunk bag but this one was the clear winner as it has the perfect size for my battery and has an external compartment for the switch and fuse. Btw, I got the fuse and switch box from Radio Shack.
