Great idea Lesley, never even thought of that.
Can't do a thing without my glasses and yep light is a major factor, but spoke to my DH about it and he will actually.....give...yes give me a small bendable LED clip on light that will actually fit on the side of the tub from his shed. Wow, tub's only about 8" wide x 12" long and 3" high not too big but perfect to fit what I need.
