How to Use a Light Keeper Pro for Easy Repairs: 1 Minute to Fix Your Christmas Lights with This Handy ToolSarah ThompsonSep 09, 2025Table of ContentsTips 1:FAQTable of ContentsTips 1FAQFree Smart Home PlannerAI-Powered smart home design software 2025Home Design for FreeDealing with malfunctioning Christmas lights can be frustrating, but the Light Keeper Pro is designed to make repairs quick and easy. To get started, first unplug your string lights and examine them for visibly damaged bulbs or broken wires. Once you’ve checked the basics, plug your lights in (if safe to do so) and look for dark sections. Insert the bulb tester end of the Light Keeper Pro into a working bulb socket to help identify where the circuit is broken. By pulling the trigger, the device sends a quick electrical pulse that helps locate and sometimes even fix the fault by bypassing bad shunts inside the bulbs. If a section lights up after you use the trigger, replace any non-working bulbs as necessary. The Light Keeper Pro’s socket tester and bulb remover features make replacing damaged bulbs easier without damaging the string or your fingers.Tips 1:As an interior designer, I always recommend using such repair tools not only to extend the lifespan of decorative lighting, but also to keep your seasonal setups looking their best.
