I recently got back into cycling after a several year hiatus. I dragged out my old gear and have a VistaLite VL-300 red rear light/flasher (my wife calls it my butt flasher ) that I have questions about. I've looked online and know that VistaLite doesn't exist anymore, and can't find a manual, if it even existed. If someone has a pdf of the manual, or could tell me about the modes on it, I would be very appreciative.

The switch seems to have four modes:

-Off
-Unknown
-Flash
-Steady on

It's the "Unknown" mode that I am wondering about. I can't remember what if anything that it did. If it should, it's not a big deal, but I might look deeper to see if I can fix it. If it doesn't do anything, so much the better.

Thanks for any info you can provide.
