Short answer: usually yes, but it depends on the specific set — some LED strings use replaceable bulbs in a socket, exactly like older incandescent strings; others use bulbs permanently fused to the wire, which aren't user-replaceable at all. Here's how to tell which one you have. How to tell if your bulbs are replaceable…

If your outdoor lights worked fine and then stopped right after rain, moisture reaching a connection or a GFCI outlet doing its job are the two most likely causes — in that order of how easy they are to check first. Step 1: Check for a tripped GFCI first If your outdoor outlet is GFCI-protected…

A dedicated circuit tester speeds this up, but it's not required — you can find a dead section on most strings with nothing but a visual check and a process of elimination. We don't currently carry a tester tool in our catalog, so here's the no-tool method. Step 1: Check the fuse first — it's…

If an entire string is dark — not just half — a blown fuse in the plug is the single most likely cause, and it's a two-minute fix if you have a spare on hand. (If only half the string is dark, see our separate half-string troubleshooting guide instead — different symptom, different cause.) Step…

Half a string going dark almost always means one of three things: a blown fuse in the plug, a loose or dead bulb at the exact point the circuit breaks (on older incandescent-style wiring), or a bad connection at a splice or connector. Here's how to find which one, in the order that fixes it…

Flickering is a different symptom from a fully dead section — the string is working, just inconsistently. Here's what actually causes it, roughly in order of likelihood. 1. Voltage drop from exceeding the connect limit The single most common cause: too many sets daisy-chained together past the manufacturer's listed connect limit. Voltage drops progressively down…
