Hey, I found a nifty way to get a longer visor on a bicycle helmet-perfect for the laid-back position of the recumbent rider. Check out SPECIALIZED spare visors for BMX bike helmets http://www.specialized.com/us/en/bc/SBC ... 0&eid=4952
I got this one, I easily attached it to my helmet with three zip ties! The visor is approximately 6"x6", and sticks out from my helmet approximately 4". Perfect for those rides that head into the sun!
