How do I repair my solar powered outside lights?

Unfortunately, as there are no consumer standards in place for pathway solar lights, there is a great deal of variance in quality, brightness, and lifespan of the fixtures. This can be frustrating and annoying.

If the covering over the bulb is plastic rather than glass, then it will probably be more cost effective to just 'retire' them and replace, rather than try to fix.

Keep in mind that the efficiency of any solar light depends on the maximum time that the sensor is covered by direct strong sunlight, and the degree to which the housing in airtight and waterproof.

Sometimes the batteries inside them have lost their charge -

often because the contact points have gotten corroded. Try pulling out the batteries and cleaning up the contacts. If that doesn’t work try new batteries.

Along with changing or cleaning batteries, I painted my solar cells with clear nail polish. Worked like a charm. Additionally, when the sun is low in winter, I move my lights to locations where they get more light. This helps keep the batteries well charged. My batteries will last up to two years. For instance on one path, in the winter I move them 6' over to the top of a fence. This worked great and the light cast from higher up reaches the walk way. In late spring they go back in the ground next to the path.
