This is very easy to use and seems to work at all points along the fence. Review: This indicator is perfect. It was actually telling me my charger was 99% dead. - I thought this flasher was broken. It was actually telling me my charger was 99% dead. I've only used it for 3-4 weeks, and now that I replaced the charger (with slightly more power to drive this flasher), the flasher is easily visible at the right angle. I think I could see it 100 feet away in daytime. Probly a half-mile at night. This indicator is perfect. Great device, good value, easy to use. LATER: sometimes it flashes at half-rate (like it misses every other flash). I have no doubt that the fence is still effective, whether the charger is missing a pulse, or the ground is too dry, or whatever. The remaining flashes are clear. ## Features - Wide range of uses: The pulse flash signal light is suitable for all pulse power supplies and any type of electric fence, including steel wire, aluminum wire, polymer wire and tape. The tape width can be up to 40mm. The use range is wider - Easy to use: Just clip the fence indicator on the electric fence. Insert the probe into the ground and it will flash with each fence pulse when the fence is working. This voltage indicator uses the power of the fence, so no batteries or additional power supply are required. It can be placed anywhere on the fence - Humanized design: The oval shell design is more ergonomic. The smooth surface will not hurt your fingers. The environmentally friendly green color blends into the external environment. The high-visibility yellow clip with anti-slip pattern will not slip even in extreme weather - Cost saving: There are 3 high-brightness LED lights inside to ensure long service life and higher brightness. The visibility is up to 100 meters at night and up to 20 meters during the day. The sealed weatherproof shell is waterproof and UV-resistant, durable. Continuous monitoring, no need to reset. If the voltage is lower than 2000V, the electric fence indicator will stop flashing - After-sales service: If you have any questions, please contact us and we will solve it for you as soon as possible ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.1 out of 5 stars 149 Reviews | ## Images ![2 Pack Detects Electric Fence Energizer Pulse Flash Signal LED Light | Tester Indicator for pulsed energizers | Alert Device That Clips to Wire or Tape Fences - Image 1](https://m.media-amazon.com/images/I/61DskkdgSpL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good cost *by S***M on March 6, 2026* My old one quit working. This is very easy to use and seems to work at all points along the fence. ### ⭐⭐⭐⭐⭐ This indicator is perfect. It was actually telling me my charger was 99% dead. *by E***H on July 10, 2023* I thought this flasher was broken. It was actually telling me my charger was 99% dead.

The remaining flashes are clear. ### ⭐⭐⭐⭐⭐ Wonderful way to tell at a glance, condition of fence *by P***R on October 22, 2023* This indicator is so easy to install, just clips onto the wire and you run it's little ground rod into the soil. It's very bright and I love that I can look out my window and see it flashing day or night. I bought two for different sections of the fence, but am going to buy more. Deer ran into a section of my fence that's close to their path, but since putting one of these there, it's not happened again. My fencing runs into the woods, so will be spacing these along the back line. --- ## 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.tn/products/723720126-2-pack-detects-electric-fence-energizer-pulse-flash-signal-led](https://www.desertcart.tn/products/723720126-2-pack-detects-electric-fence-energizer-pulse-flash-signal-led) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-08*
