Strainrite Fence Flasher – Blue (for Stainless Steel Wire)

The Strainrite Fence Flasher gives you a standing visual read on your fence line. It runs on the fence's own energy — no batteries, ever — and the flash rate slows as fence voltage drops, so a glance down the line tells you the fence is live and how well it's holding.

Visible up to 1 km (about 0.6 miles) at night and 100m (330') in daylight, it's the fastest way to confirm a fence is hot before moving stock, or to keep an eye on a new installation without walking the line with a tester every time. This blue model is made for stainless steel wire; Strainrite's dark grey version suits galvanised and aluminium wire.

Features

Battery-Free Operation: Connects between the live wire and earth and draws minimal power from the fence — nothing to replace, nothing to maintain.

Flash Rate Shows Voltage: Normal flash above about 7.5 kV; 25% slower between 7.5 and 3 kV; 50% slower between 3 and 2.5 kV; 75% slower below about 2.5 kV. The longer the gap between flashes, the lower the voltage.

Visible 1 km at Night, 100m by Day: Highly visible LEDs with a 160° viewing angle — readable from across a paddock, not just straight on.

Wide Operating Range: Works from 0.9 kV up to 12 kV and is compatible with most electric fence energizers.

Blue for Stainless Steel Wire: Colour-matched to the wire type it's designed for.
