Found these the other day in B&M bargains. for fiddly stuff they are very good, especially if working with SMD and are very sturdy for bigger stuff. Obviously intended as a beauty product but looks at home in my tool box.
Has a single blazingly bright white LED pointing between the middle of the tweezers, powered by 3x AG3 cells and a simple push-on/push-off switch.
Bargain for 99p.
