Reading light for goggles

Reading in the dark?Reading in the dark is a bit tricky. By using this little attachment on your reading goggles it is possible to read even after sunset. A bonus is that your spouse can have a good nights sleep. I used a cheap reading light as the base for this project but I guess it is possible to use a led, a spring from a pen, a wire and some soldering. The battery cells is LR41, they are small and easy to carry but maybe the power drops a bit to fast. One idé is to use LR44 instead but then to whole attachment will be heavier and a bit more clumsy. The print on a Bambu A1 mini with fine settings makes the whole thing looks great. It is takes bit of fiddling to get everything in place but once together it works great.
