I spotted a really nice tail light this morning and haven't been able to figure out a make. It's a dual red led on the back, one solid, one slow pulse and two side facing flashing yellow leds (right and left). Has anyone else seen one of these?

Topeak mega?

maybe this fella?

Looks like a nice stuff. However, it sells for $80+. For the same price, one can instead buy 3 brighter lights and install them in different directions to get the same (even better) effect, as this little light doesn't seem to be super bright?

I checked on both and they're not it. This was a clean solid red with a second red on at a slow flash and no yellow bleed over. I didn't even see the yellow flashers on the sides until we were at different sections of a long turn. Unfortunately he's a bike ninja and I don't see him until he's passed by otherwise I'd just ask him.
