I'll never forget, about 15 years ago at a friend's party, he needed help assembling a foosball table and handed me a headlamp. I went out and bought one the next day.I'm glad you mentioned the light! Good lighting is often overlooked or taken for granted but is one of the most important components of work safety/efficiency. I recently switched almost exclusively to a Coast rechargeable headlamp even when I'm using my favorite tool (a BFH).
The developments in LED lighting over that span have been absolute game changers as well.
