We have searched high and low for a red or green colored pen that illuminates the writing entire writing surface, not just a few letters at a time like some popular navigation pens do.... and we wanted one that writes smoother and is more durable than the competition.
This unique light pen incorporates a small red or green LED, which is tucked into the top of the pen (near the clip). Twist the pen bottom to write, click on the top to activate the light. Use the pen at night to make a log entry without having to hold a flashlight with one hand as you try to write with the other. The LED Light Pen runs for hours using three small button batteries, which are located in the top of the pen.
This pen is the perfect solution for watch on the bridge of a ship at night.
