The Clever Collar will shed some light on your work. Simply slip it over the business end of your screwdriver, rotate the ring, and you will have three powerful LEDs to make the workload lighter.
Flexible center hole slides onto any manual screwdriver from 3/16″ – 7/16″ diameter, or onto cordless 1/4″ powerdrivers. Also doubles as a handy inspection light with strong internal magnets to hold it in place.
The LED Clever Collar is available from Herrington for $14.95.
