I also like running a backup taillight because if one goes south on you, and I have had that happen, or bounces off, and I've had that happen too, you might not know. At least not right away.
Thanks! I did a search for the light on Google, and the first result was this:

I think I may do mod #6 listed there to make the LEDs brighter. I'll see once it arrives. BTW, does the light use AAs or AAAs? The company site lists AAA, but the eBay seller has AA.
