I didn't like this at all at first but then I kept looking at #12-13 and liked the circle. Still not sure about the stop light lens but let me stare at if a little while longer.
On #8 and #9 I just don't think there will be enough room to put "auto recycling" in the logo. I prefer it outside. Can you try one with the "auto recycling" even larger. I would also like to see one with the GO in Caps...same font. I like the circle and think this would look good on several mediums.
Can you please put this on a white backgrond only. that way I can judge them all fairly. These will go on a variety of items so white is the best neutral color.
