Loc-Lite is an LED light that is said to stay where it is put and be bright. The stainless steel light is waterproof and requires only a twist to turn it on or off. The batteries last for more 100 hours, and the rubber-coated magnet will not scratch painted surfaces, according to the company. Its small size, says the company, makes it easy to put light in a difficult constrained location. All light components are in the stainless steel body, so the flexible length can be adjusted simply by snapping apart.
A flashlight on a detachable key chain is also available, and both lights can be ordered with a red LED.
