Outdoor Light Fixture Not Working: Causes & Fixes
Outdoor light fixtures stop working for three main reasons: a burned-out bulb, a tripped circuit breaker, or a loose wire connection. Most fixes cost under $15 in replacement parts and can be completed in under 30 minutes without calling an electrician. This guide walks you through diagnosing the problem and restoring power to your outdoor lighting.
Step-by-Step Fix
- 1
Check the bulb
Turn off the light switch and wait 2–3 minutes for the bulb to cool if it was recently on. Carefully unscrew the bulb from the fixture and inspect it for a black burn mark inside the glass or a broken filament. Replace the bulb with a new one rated for outdoor use and screw it back in firmly.

Test the circuit breaker
Go to your home's electrical panel and locate the breaker labeled for outdoor lights or the room where the fixture is installed. Check if the switch is in the OFF or tripped position (usually halfway between ON and OFF). Flip it fully to OFF, then back to ON. Return to the light and test if it now works.

Inspect the light switch
Turn the wall switch on and off three times and listen for a click or feel for resistance. If the switch feels loose, sticky, or makes no sound, it may be faulty. Test another light on the same circuit to confirm the switch isn't the problem.

Check for loose connections at the fixture
Turn off the circuit breaker completely for safety. Unscrew the fixture's cover plate or trim ring to expose the wiring connections. Look for any black or white wires that are loose, disconnected, or corroded green. Gently push wire connectors together if they're loose, and tighten any wire nuts by hand.
- 5
Test with a voltage tester
Use a non-contact voltage tester (available at any hardware store for $10–$20) to confirm power is reaching the fixture. With the breaker ON, hold the tester near the wires inside the fixture. If it beeps or lights up, power is present. If not, the problem is upstream and you should call a professional.
⚠️ Safety Notes
- Always turn off the circuit breaker before touching any wires inside the fixture to avoid electrical shock.
- Never work on outdoor electrical fixtures in wet conditions or while standing on wet ground.
- If you smell burning plastic or see scorch marks around the fixture, stop immediately and call a licensed electrician.
When to Call a Pro
If the circuit breaker keeps tripping after you reset it, if the voltage tester shows no power reaching the fixture, or if you see burned or melted wires, stop work and contact a licensed electrician—these indicate a serious wiring fault.
Frequently Asked Questions
- Why does my outdoor light fixture keep burning out bulbs?
- Outdoor fixtures often burn out bulbs because they lack proper ventilation or the wrong bulb wattage is being used. Always use bulbs rated for your fixture's maximum wattage and designed for outdoor wet locations, which typically last 5,000–25,000 hours.
- How do I know if a circuit breaker is tripped?
- A tripped breaker will be in the middle position (between ON and OFF) or fully switched to OFF, while other breakers around it are ON. Flip it to OFF first, then back to ON to reset it.
- Can I replace an outdoor light fixture myself?
- Yes, if you turn off the breaker and the fixture is not hardwired directly to the wall. Most bolt-on or clip-mounted outdoor fixtures can be swapped in 10–15 minutes, but hardwired fixtures should be replaced by a licensed electrician.
- What does it mean if my outdoor light flickers?
- Flickering usually means a loose bulb, a failing bulb reaching end-of-life, or a loose wire connection at the fixture. Tighten the bulb first, then inspect connections inside the fixture.
- How much does it cost to fix an outdoor light that won't work?
- Most DIY fixes cost $5–$20 for a replacement bulb or a new wire connector. If you need a new fixture, budget $30–$150 depending on style; professional installation adds $50–$150 in labor.
