A retail site called Your-Flashlights.com has the best deal online for the Streamlight Stylus LED Pen Light at $13.95. The pen is 6.21 inches long with a waterproof black aluminum body and a pocket clip. The manufacturer claims it runs up to 60 hours on three AAAA batteries (included in purchase). You also get two settings: blinking or a standard “on” switch.
What’s really cool about this stylus is its red LED pen light can be seen from over a mile away. If you work outside at night, go on midnight earthworm hunts for fishing bait, or enjoy amateur astronomy, you know that red light allows you to direct someone’s vision or illuminate an object without the glaring effect and temporary vision loss that comes with standard lights.
The bottom line: Want to see in the dark with no glare? Go red. And for $14 you can readily pick one up and keep it handy for late-night stargazing.
