Spent the entire weekend (18hrs) working on my engine and i came up w/ a great way to provide light after we lost power at midnight and i had RTV down requiring my manifold be put together within 30mins. Would work great for oil changes etc when the hanging shop light just doesnt cut it, as well as other places. 1 baseball cap + 1(or2) small LED Light(s) w/ a belt clip = hands free light. Ill post a pic, but its pretty easy to imagine. I had enough lights for me to have 2 on my brim and 1 on my girlfriends hat. Just tighten the hat a little to account for the extra weight (i use energizer lithiums so battery weight is minimal) I wish i would have thought of it years before because its extremely handy and free.
