Why LED Outdoor Lights Flash And How To Fix Them
Quick answer: Outdoor LED lights usually flash because of a photocell seeing its own light, a motion sensor retriggering, moisture in the fixture, an incompatible dimmer/timer, a failing driver, or unstable wiring. Start with pattern diagnosis: dusk-only, rain-only, motion-only, warm-up-only, or random flashing.
