i'v had mine for 9 months and it BROKE! the light would flicker or not come on. i changed batteries and it flickered. i took the handle apart ant the very tiney ?led( light bulb) fell out of the two very tiney holes into which it was inserted. one prong was bent, so i straightened it and reinserted...same problem, so i called the 800 no of parent co...i DID mail in my warranty registration. i was advised that a replacement light source bulb was in the handle screw cap in a red plastic holder. VOILA! IT IS TINEY . replaced the old with the new and YAHOOO! I have light!!! the instructions didn't mention this extra bulb so i thought i'd report my experience in case others have the same problem. a reall great tool!
