I've seen a few cyclists around town with these and, for as low power as they are, they are remarkably eye catching. I think that it's the combo of a steady, non-blinking light that is moving erratically (in relation to other traffic). There are also a number of valve stem lights available that produce a similar effect; just Google "valve stem light".

But if you want to go with the Cadillac of spoke lights, then you should give the Monkeylectric Monkey Light a try. Don't let the images on the website fool you, you don't get the full wheel effect with one light until you're spinning at +25 mph; and I recommend two lights anyway, to balance out the spin weight (the lights themselves are lightweight, but at three AAs per light they can get pretty hefty when loaded), and to look cooler when you're riding around 10-20 mph. You can pick which colors and patterns you prefer (so if you want just yellow and white, no prob), and they're wicked bright, so even if you aren't moving fast enough to display the patterns, you're still very visible.




Less bright, flashy, and expensive is BikeGlow, which you can get in yellow, or a variety of other colors. My lady runs this on her bike:




Regarding mounting the Dinotte to a trunk bag, I'd try PM'ing 10wheels about it. He runs a Dinotte and a trunk bag, and I've seen images of his Dinotte taillight in various configurations.
