Welcome aboard Don. I have a lightbar and the visors on all three lights. Before I had them, I got quite a bit of wind buffeting. The visors helps a lot. The headlight one I got from Ma's Cycles and is the 7" one (it's been awhile, so if anyone knows I am wrong here, chime in!!). Here's the link to the visors:

Here's the best pic I have of the visors:
