Very cheaply made. Its not even close to my snap-on test lights. Not even heavy duty like they say. I used mine for the first time and it failed. **Q: When I got one it didn’t come with a replacement bulb. Did anyone else have same issue?** A: Mine came with on. **Q: will this work on 24 volt furnace testing thermostat** A: I'm pretty sure it will I don't think 24 volts will burn out the bulb. Use it on DC only AC might be too high of a voltage for the bulb. 24 volts is DC I think there are even some 48 volt DC circuits. I would use it on those too **Q: Is it safe to use on electronics?** A: Yes. As long as they are 15VDC and below ## Frequently Bought Together - Heavy Duty Automotive Circuit Tester, Premium 6-24V Test Light with Extended Spring Test Leads & Sharp Piercing Probe, Circuit Voltage Tester with Replacement Indicator Light for Car/Vehicles - JOREST 300Pcs Car Fuse Assortment Kit, 160 Mini Blade Fuses Automotive + 90 Standard Auto Fuses + 50 Micro + Puller – Replacement for RV Camper Boat Truck (2Amp 3A 5A 7.5A 10A 15A 20A 25A 30A 35A 40A) - Heavy Duty 3-65V Backlit Digital LCD Circuit Tester, Test Light with 140 Inch Extended Spring Wire, Car Truck Low Voltage & Light Tester with Stainless Probe --- ## 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.gr/products/127926312-heavy-duty-6-24v-automotive-circuit-tester-w-replacement-indicator](https://www.desertcart.gr/products/127926312-heavy-duty-6-24v-automotive-circuit-tester-w-replacement-indicator) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-07*
