I found an LED light at Harbor Freight for only a few dollars. It has a forward-looking three- light reflector on one end and a "hangup hook" at the other, then one flat side has 24 LED lights (super bright!) and a strong magnet on the reverse.
It's great if I'm not trying to stuff a quilt under the arm. For normal sewing, it's like having a ray of sun in the sewing area.
Here's a link to it:
