When your outdoor lighting stops working, the problem is almost never what you think it is. Rob Bingham of Outdoor Lighting Perspectives walks through the exact troubleshooting process our technicians use on service calls across Everett, Snohomish, Mukilteo, Bothell, Mill Creek, and the broader North Sound area.
Watch the full walkthrough video below, or read on for the step-by-step breakdown.
Start at the transformer — always
The transformer is the brain of your low-voltage outdoor lighting system. Before assuming a fixture is dead or a wire is cut, check that the transformer has power. If it's connected to a smart outlet or Wi-Fi switch and that switch shows as active, you have power at the outlet.
Open the transformer door and look at the internal toggle switch — this is the built-in circuit breaker. If it's tripped, reset it. A tripped breaker means the system detected an overload — a short somewhere in the yard, a bad fixture, or a damaged wire. The breaker doing its job is actually good news. But it also tells you there's more digging to do.
Isolate the problem zone
Most professionally installed North Sound lighting systems are divided into two or more zones. Here's what to do:
- Disconnect one zone from the transformer by pulling its wire out of the terminal
- Reset the circuit breaker and see if it holds — if it stays on, the problem is in the zone you disconnected
- Walk the yard — lights that are on belong to your good zone; lights that are off belong to the fault zone
Work upstream — cut the problem in half again
Find a connector roughly halfway through the problem zone and disconnect it. Reset the breaker. If it holds, the fault is in the second half. If it trips again, the fault is in the first half. Keep cutting in half until you isolate the specific fixture, wire, or connection.
Check individual fixtures and bulbs
- **Bulbs** — pull a few and inspect; burnt or blackened bulbs are obvious but a bulb that looks fine may still have a failed LED driver
- **Fixtures** — look for water intrusion, cracked housings, or corrosion; moisture is the biggest enemy in the North Sound climate
- **Wire connections** — look for exposed wire nuts, loose connectors, or green corrosion at connection points
- **Water feature lights** — fountain and pond lights are a frequent cause of circuit breaker trips; a compromised seal creates exactly the kind of short that trips the system
When to call a professional
If the system is still tripping after working through these steps, or if you find significant wire damage, corrosion, or a transformer that looks burnt or damaged, it's time to call in a professional. Our team services systems across Everett, Snohomish, Marysville, Mukilteo, Bothell, Mill Creek, Lynnwood, Edmonds, and surrounding North Sound communities — regardless of who originally installed them.

Frequently asked questions
Why does my outdoor lighting transformer keep tripping the circuit breaker?
A tripping circuit breaker almost always means there's a short somewhere in the system — usually a damaged fixture, a failed seal on a water feature light, a corroded wire connection, or a cable nicked by a shovel or edger. The fix involves isolating the problem zone, then working upstream to find the specific fault.
Can you repair my outdoor lighting system if it wasn't installed by Outdoor Lighting Perspectives?
Yes. We service and repair low-voltage landscape lighting systems across the North Sound area regardless of the original installer. Give us a call at (425) 428-6309 — we'll diagnose the issue and get it running correctly.
How long does an outdoor lighting repair visit take in the Everett area?
Most residential repair calls in the North Sound area take one to three hours depending on the complexity of the system and how quickly the fault can be isolated. A system with clearly defined zones and accessible wiring is faster to diagnose than one with buried connections or multiple simultaneous failures.
