Hm that looks like an Evo Lite that Calhoun lists which caught my eye the other day.
They have numerous amounts of extensions and mounts for it.

It was early enough I don't see much traffic so that was good.
It wasn't actually foggy till I got to lakeside approaching 121 and I thought it was just going to be there and over on royal for a mile or two like usual but today it was solid fog the whole way except for a couple clear spots. When I crossed over 114 I could not see the cars on the highway. I heard them so I know they were there but I could barely see their lights.
Early in the fog I think a trucker took pity on me, or couldn't see the road himself, and followed me down lakeside instead of changing lanes. I was going at a pretty good clip at that point since I know the road so well and when a car passed on the left he was only going a few mph faster. I actually caught up to a few cars on some back roads near beltline that were either lost or had difficulty seeing.
With the dinotte on high/low flash, superflashes solid and much more reflective material then I had when that pic was taken I was pretty visible but kept out of the way when cars approached. I do wish I had setup my lightman amber strobe though. I still had cars stopped at side streets to let me pass when I approached so they saw me from the front also.
The most dreaded part of my commute was a no show. Going up royal to cross mcarthur, stop light on a busy hill, the light turned green when I was 100ft away and I made it through before it went red.
