By Andrew Liszewski It’s just another concept at this point, but Jeong-Sun Park’s Knob Light will be appreciated by anyone who tends to wander the house at night. It’s basically a replacement door knob in the shape of a glowing light bulb, making it easier to find your way around when the lights are all off. There’s no specifics on how the

bulb is supposed to get power, since doors aren’t usually wired for electricity, but I’m pretty sure it will use LED based bulbs instead of incandescent ones because of the whole hot glass vs. skin issue. [ Yanko Design - A Knobby Light ] VIA [ Toxel ]
