It’s more for finding the cable pathway, but could help find a dead short. **Q: Can this unit trace wires that are in flex?** A: Yes **Q: Can I trace from a light fixture back to a switch? (I can not find how to turn on a few lights in my new house)** A: this tracer work's better on energized circuits but will also work with de-energized circuits. if your light is not energized, then hook up the transmitter to it and then use the receiver to follow the wire through walls and ceilings to find your switch. You may have to set the detection level higher on the receiver for this use. **Q: Will this tracer generate an audible tone when connected to 14/2 speaker wire?** A: Don’t know. I’m deaf and just look at the visual readout. ## Frequently Bought Together - Klein Tools ET450 Advanced Circuit Breaker Finder and Wire Tracer Kit for Energized and Non-Energized Breakers, Fuses, and Wires - Klein Tools RT390 Circuit Analyzer with Large LCD, Identifies Wiring Faults, GFCI and AFCI Tester, Voltage Drop, Displays Trip Time - Klein Tools 69411 Circuit Breaker Finder Accessory Kit, Circuit Breaker Leads and Adapters --- ## 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.sg/products/503630094-klein-tools-et450-advanced-circuit-breaker-finder-and-wire-tracer](https://www.desertcart.sg/products/503630094-klein-tools-et450-advanced-circuit-breaker-finder-and-wire-tracer) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-11-01*
