Fix Christmas Lights

It’s that time of year when our allotment of swear words gets used up messing with fussy Christmas light. How often have you spent what felt like hours tracking down defective bulbs on your light strings. Well there is a solution that provides an easy way to fix Chritmas LIghts


The folks at Ulta-Lit Technologies have come up with the LightKeeper Pro an inexpensive tool that will will put an end to your Christmas lighting woes.


First a look at the problem..modern light sets eliminate the problem of one bad bulb affecting the entire string by installing a shunt in the bulbs so that when the filament fails the shunt kicks in leaving the other bulbs lit. Sadly it doesn’t always work. That’s where the LightKeeper pro steps in. Simply remove any bulb, plug in the LightKeeper Pro and pull the trigger which gives the defective shunt a kick until it kicks in and  the lights come on.

Once the shunt is activated you can quickly spot the defective bulb and replace it. Now what if the shunt fails or it is a loose bulb? That’s where the continuity tester comes in. Slide it along the wire until it stops beeping and Voila! you have found the non-functioning bulb. Just use the included bulb tester to verify that the bulb is really defective or just loose.

I have had the device for a couple of weeks and wouldn’t you know it not one bulb has failed so I couldn’t test the shunt zapper but I did find the continuity tester found bulbs I had intentionally loosened every time.

Here are a few tips to help make sure you have a successful and stress free Christmas Lighting season.

  • Measure: To estimate the number of lights needed for your tree, plan an average of 100 lights per every foot of tree height. Serious decorators often double that.
  • Inspect: Before stringing lights, check for broken bulbs and sockets, frayed cords, burned out lights, and loose connections. For sets with bulb outages, use the LightKeeper Pro
  • Connect: When using incandescent lights, connect no more than three strands of mini string sets together. LED light sets can handle connecting more than 30 strands together. 
  • Indoor vs. Outdoor: Commercial-grade light sets are more reliable for outdoor use because of their durability and thicker insulation. 
  • Live and Artificial Trees: When stringing lights on a tree, begin at the top of the tree and wind the strands through its center, widening with the tree’s shape. Real trees should be watered daily. When the tree is purchased, request a half of an inch be sawed off so when you get it home the tree can take in more water.

The LightKeeper Pro is available in Canada for $24.98 at Home Depot, Lowes, Canadian Tire and Home Hardware.
