A red LED head lamp would also be nice.

| On to the LED headlamps. These are made by Rayovac ("Sportsman",
| 3-in-1, model SPHTLED) and Energizer ("LED Essentials", model
| HD33A1EN). One comes from Walmart and the other from Target and I
| can't remember which. The Rayovac model has 3 lamps: white LED, red
| LED, and white incandescent; the Energizer just 2 lamps, white and red
| LED. They are both designed to wear on your forehead so you can work
| hands-free.

| somewhat harder red LED pattern; the Energizer just the opposite. My

| then turn it off, still wearing it, and have it available as a backup
| during flight.
