LED-sovellutuksia


Christmassy touch to your garden with these solar-powered fairy lights
.They feature 50 bright white LEDs, and charge automatically during the day to give you around 9 hours of light at night. They will set you back $29.95, which is a little steep, but the bulbs will last 10,000 hours which is enough for several years' fairy-lit evenings. Praying for sun around Christmastime will have never felt so normal. –



When the LED flashes at you that means you need to fill your tires up with some air. You lost about 4 cents a gallon when pressure drops below 2.96 psi so it’s worth it to know when you should be filling those rollers back up. It’s self calibrating, which is nice, but make sure those tires are up to snuff to begin with. The VECSAFE valve caps are $34.95.
