some tools have shadowed ares that would benefit from more directed light.
magnet attached flexi-light
this was the only thing my local harbor freight had, but you can use anything that flexes
use a micrometer to measure the width of the magnet and match with a drill bit
I used tape, but you could spot weld it, use stronger tape, etc.
Yea, it works
I couldn't find a battery powered, magnet mounted, flexible light, that was strong enough on amazon, so I made one.
I made it at TechShop
