I’ve really got to hand it to these people for actually building their vision of cuff lights.
Today’s invention is a simpler relative: cufflink task lights.
Personally, I’m never sure why anyone would wear cufflinks, so here is a reason. Each link would have a bright set of leds pointing in the direction of the wearer’s extended fingers (and a few watch batteries).
This would allow all the task lighting required when fine tuning the carburation on one’s Aston, en route to an evening at Glyndebourne.
