Light tight spaces when turning vessels

While turning the inside of deep vessels, I struggled to see the tool's cutting action, even while using a flashlight to peer inside. Then, it occurred to me to mount a flexible-neck penlight (woodmagazine.com/streamlight) directly to the tool. Mounted as shown, the light can be repositioned on the tool, as dictated by the shape of the vessel.
