Tracer Products offers the super-compact Tracerline TP-8640CS Optimax Jr — a cordless, blue light LED leak detection flashlight that reveals vehicle leaks in cramped areas inaccessible to larger lamps. It measures just 7¼" (19cm) long, weighs only 5 ounces (140g). This powerful, low-cost flashlight makes all manufacturers' fluorescent dyes glow brightly so technicians can pinpoint air conditioning and fluid leaks. It provides over four hours of peak performance and has an inspection range of up to 6' (1.8m). The Optimax Jr uses an LED bulb with a 100,000-hour life and comes with fluorescence-enhancing glasses in a handy clamshell package.
