Flashlights are a must for safety and convenience in any boat, car or household. For best performance try German engineered Coast lights, which incorporate a crystal lens and gold contacts. Or, select waterproof divelights from Pelican, designed to withstand the harsh elements from torrential rain or burst pipes, or a dive 500 feet underwater. Standard incandescent type lights offer economy or LED with comparable candlepower promise super long battery life. Xenon lights produce a high intensity beam that exceeds traditional performance and cuts through fog, smoke and haze. For a light that never needs battery replacement and is always ready in any emergency, try an LED Shake-Lite. These lights derive power by shaking a magneto inside the handle.
