I put up my outdoors Christmas lights which included a mini Christmas tree and 2 deer, all 3 of which had the mini lights. Well the light string on the tree would not light at all and only 1/2 of the lights on each deer lit up. Anyone that has these lights knows how frustrating it is to try and find the bulb(s) that need replacing. It is almost impossible to figure out which bulb or bulbs are causing the problem. I was at Home Depot at lunch yesterday and saw a device called Light Keeper Pro for $25 that makes the light string work again even with the burnt bulbs so that you know which ones to replace. I thought what the hell, I'll buy it and if it doesn't work I'll just return it. Well by George this device does work! You just plug the light string into the device (which has 3 batteries), pull a trigger about 10 times (which sends out some kind of energy) and it miraculously makes the electricity flow through the burnt out bulbs so that the entire string lights up and you can tell which bulbs are burnt. Now I know why millions have been sold! LOL
