And the light pen stopped working after about 2 months **Q: Does the tester make a noise when it detects that the socket is live ?** A: Yes. The small test bleeps and the red light flashes when it detects a current. The plug socket tester does not make a noise, as you might expect as your testing a live plug socket ## Frequently Bought Together - Proster Voltage Tester, Upgraded Socket Tester Non-Contact Voltage Tester Pen and Plug Tester Socket Tester kit with LED Flashlight Pre-Installed Battery with Sound and Light Alarm - KAIWEETS Wire Strippers Electrical, 3 in 1 Wire Cutters, Electrical Tools Terminal Crimper for Electricians, Circuit, Distribution Box Repair, AWG 10-22, Pressure Adjust Rotary Switch, SK5 Cutter --- ## 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.at/products/220401363-socket-tester-non-contact-voltage-tester-pen-kit-rcd-gfci](https://www.desertcart.at/products/220401363-socket-tester-non-contact-voltage-tester-pen-kit-rcd-gfci) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-10-30*
