Outdoor lighting serves important purposes like illuminating pathways, highlighting architectural features, and providing security. However, outdoor lights can develop problems that prevent them from working properly. Fortunately, many outdoor lighting issues can be fixed with some troubleshooting and simple repairs. Here’s a comprehensive guide on how to fix common problems with outdoor lights.
Inspect the Light Fixture
Start troubleshooting outdoor light problems by carefully inspecting the exterior fixture. Look for any signs of damage, corrosion, insect infestations, or moisture intrusion. Also check that the light bulb is screwed in fully and that any seals or gaskets around the fixture are intact. Identify the light source – is it incandescent, LED, halogen, solar, or low voltage? This will help pinpoint the issue.
Check the Power Source
Make sure the light fixture is getting power. For lights wired into your home’s electrical system, confirm the circuit breaker is switched on and hasn’t tripped. Toggle the breaker off and on to reset it. Test any outlets the light is connected to. Ensure any switches that control the outdoor lighting are working.
For solar lights, check that the batteries are charged and installed correctly. Look at the solar cells to see if they are clean, facing the sun, and unobstructed. With low voltage lighting, inspect the transformer and timers.
Replace Light Bulbs
Burnt out light bulbs are the most common cause of outdoor lighting failures. Replace bulbs that are no longer illuminating. Match new bulbs to the wattage and type listed on the fixture. When changing hard-to-reach bulbs, use a telescopic light bulb changer.
LED and CFL bulbs last longer than incandescent but do eventually stop working. Replace the entire LED or CFL fixture unit when the bulbs go out.
Clean Fixture and Bulb Contacts
Buildup of dirt, grime, and corrosion on the bulb and socket can interrupt the flow of electrical current. Clean bulbs with isopropyl alcohol before reinserting. For the socket, turn off power and gently remove debris with a cotton swab soaked in rubbing alcohol.
Adjust Motion Sensor Settings
Outdoor security lights with motion sensors have adjustable settings like sensitivity and duration. If the light isn’t coming on, point a moving object at the sensor to test it. Refer to manufacturer instructions to change the motion sensor settings as needed.
Fix Moisture Issues
Moisture getting into fixtures can lead to corrosion, electrical shorts, and bulbs burning out prematurely. Apply weatherproof silicone caulk around any cracks and openings in the fixture housing. Replace any damaged rubber seals. Move the light away from sprinklers spraying water onto the fixture. Install a cover over top of the light to shield it from rain and snow.
Check Wiring Connections
Problems like flickering and dimming lights may indicate loose wiring connections. Turn off power to the fixture at the breaker. Take the fixture down and use a voltage tester to confirm power is off. Remove the cover and check that all wiring connections are tight and corrosion-free. Rewire any loose connections and use electrical tape to insulate exposed wires.
Replace Rusted Fixture Housings
The metal housing of outdoor lights takes a beating from weather exposure. Rust and corrosion mean it’s time to replace the entire fixture. Choose a new housing rated for outdoor use with features like weather/rust-resistance and a sealed design. Install the new fixture base securely over the existing electrical box.
Reset Circuit Breakers
Circuit breakers serve as the power switch and safety trigger for lighting circuits. Start troubleshooting with resetting the breaker controlling the outdoor lights. Flip the switch off and then back on. If the breaker immediately trips again, there may be a short in the system. Contact an electrician if resetting the breaker doesn’t resolve the issue.
Fix Low Voltage Transformer Issues
Low voltage lighting relies on a transformer to step-down 120-volt current from the house to 12 volts. If low voltage lights are malfunctioning, problems with the transformer are likely the culprit. Inspect it for damage, overheating, or blown fuses. Ensure the timer and photocell sensors are properly adjusted. The entire transformer may need replacement if issues persist.
Invest in Surge Protection
Power surges from storms or faulty wiring can overload and fry outdoor lighting systems. Install surge protector strips designed for outdoor use to safeguard lighting circuits. Place them at the service panel, on specific circuit breakers, or at the first outlet the lights are connected to. Surge protectors will prevent voltage spikes from reaching your outdoor lights.
Call an Electrician for Major Issues
Contact a licensed electrician for outdoor lighting problems involving potentially hazardous electrical faults. Signs like frequently tripped breakers, burned out wires, and flickering lights indicate an electrical issue. Faulty wiring in the light circuits needs to be examined and repaired by a qualified electrician. They have the proper training and tools to diagnose and fix major problems.
Frequently Asked Questions About Fixing Outdoor Lights
What are some common problems with outdoor lighting?
Some typical issues include burnt out bulbs, moisture getting into fixtures, damaged wiring, problems with motion sensors, and corrosion on metal housings. Solar lights can have problems recharging batteries or faulty solar cells.
Why do my outdoor lights keep blowing fuses?
Frequently blown fuses indicate a short circuit somewhere in the lighting system. This is often caused by old wiring with damaged insulation and exposed wires touching. An electrician should diagnose and repair the wiring before replacing more fuses.
Why does my motion sensor light stay on all the time?
The motion sensor may be picking up constant movement like tree branches swaying. Try adjusting the sensitivity, swivel angle, or range of the sensor to avoid non-motion triggers. The sensor may also need cleaning if dusty or covered by cobwebs.
How do I stop my outdoor light bulbs from burning out so quickly?
Use LED or CFL bulbs that last much longer than standard incandescents. Install fixtures with sealed designs to protect bulbs from moisture. Place lights away from areas where water directly sprays onto them. Surge protectors also prevent premature bulb failure from power spikes.
Why does my low voltage lighting dim and brighten randomly?
Faulty wiring connections that are loose or corroded can cause uneven power flow and flickering with low voltage lights. Inspect connections at the transformer, in junction boxes, and at the light fixtures. Clean and re-secure all loose wires.
Should I repair or replace old outdoor light fixtures?
If an outdoor fixture is very outdated or damaged, replacement is better than repairs that may not last. Newer outdoor lights are designed to be weather-resistant and easy to maintain. Choose an ENERGY STAR-rated LED fixture for efficiency and long life.
Conclusion
Troubleshooting common problems like burnt out bulbs, sensor adjustments, electrical faults, and moisture intrusion can help resolve many outdoor lighting issues. Simple repairs like replacing bulbs and cleaning fixtures go a long way. Seek professional help for major wiring problems or extensive corrosion. Investing in modern, weatherproof outdoor lighting equipped with surge protection and LED bulbs will improve efficiency and minimize future issues. With some diligent maintenance and repairs when needed, your outdoor lighting system can continue shining brightly for years to come.
