This is a very complicated and expensive device that has been invented for the sole purpose of extracting cash from those that know nothing about vehicle maintenance and call a Dial-a-mechanic to help change a tail light bulb. It looks like a cross between a welding mask, a pair or electricians’ pliers and a King Charles Spaniel.

For head light bulbs you need the even more expensive grunge-pinion fitting as well, which stops you skinning your knuckles. It’s a pair of welding gloves.

(With apologies to knowtion for disruption to their idea.)

I suspect the alternative medicine industry have a patent on this business model.
