The voltage detector will not reliably work with LED light strings. Please check your light string type before use. **Q: Can I find the bad bulb without taking every single one out?** A: It requires you to remove and test each bulb individually for a precise diagnosis. It is not a "non-removal" type that scans the entire string. While it takes a few minutes, you find the exact faulty bulb or fuse, saving the entire set. **Q: The voltage tester pen beeps when I turn it on near an outlet, but doesn't beep for my lights. What's wrong?** A: It is a common issue with a simple fix! First, please ensure you have removed the battery insulation strip and the batteries are installed correctly (check the +/- polarity). If the problem persists, try replacing the new LR44 batteries. **Q: The electrical tester pen sometimes beeps for no reason. Is it broken?** A: This is likely due to high sensitivity picking up ambient electrical interference. Try turning the sensitivity knob to a lower setting. Avoid using it directly next to other powered-on electronics or dense clusters of wires to prevent false alarms. **Q: How do I use the bulb remover tool?** A: Slide the switch to extend the fork. Insert between bulb and base until loose, then pull out by hand. For "lock-in" bases, gently twist to unlock first. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great little tool! *by M***R on November 18, 2025* At first we were going to send it back because it was glitchy. We were able to get it working properly. Great little tool! ### ⭐⭐⭐⭐⭐ Fix lights *by M***N on October 29, 2025* Easy to use. And was able to fix lights ### ⭐⭐⭐⭐ Bulb remover doesn't work on my bulbs *by D***N on January 3, 2023* This is basically a current tester with an added bulb/fuse tester and bulb remover. The current tester and bulb/fuse tester seem to work fine. The remover is too thick to use on my bulbs. But I found that a General #69 wire stripper works great for this purpose and is inexpensive like this tester. The fuse tester works with the tiny fuses that came with my light set. Wouldn't work for car fuses. It seems handy for working with the light sets on my fake tree. ## Frequently Bought Together - allsun Christmas Light String Tester Non Contact Voltage Finder Meter Light Bulb&Fuse Checker Gun 12-600 V AC Mini Light Repairing Tool, NOT Suitable LED Light String, Blue - Mudder 60 Count Replacement Christmas Tree Light Bulbs 2.5v 0.425 Watt Replacement Light Bulb Mini Incandescent Wire String Lights Decoration for Prelit Xmas Tree(Green Base with Warm White Bulb) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/90344299-allsun-christmas-light-tester-with-bulb-remover-and-fuse-tester](https://www.desertcart.vn/products/90344299-allsun-christmas-light-tester-with-bulb-remover-and-fuse-tester) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-16*
