It would appear that the lights are getting moisture in them
We have found that they only way to keep moisture out of them is to use silicone paste, not silicone sealer, on the rubber seals and gland seals - The paste to rubber is like Dubbin to leather
Silicone sealer tends to shrink when it gets cold and allows water to stream in.
The 2nd thing that needs to be done is to excavate a hole the size of a 5 litre paint can or bigger, depending on the soil, below the uplighters and fill with coarse stone and then fit the uplighters. This allows for any water to soak away and not sit around the light fitting. When a light is on it gets warm and as soon as it is switched off it cools down and sucks water in , how or where is always a mystery - The stone trick generally works but if the soil has a lot of clay you always run the risk of getting water into the fitting .The only way is to have drainage to keep the fittings out of a " pool " of water from underneath.
The look the fittings give in lighting up is always aesthetically pleasing but from a practical point of view a nightmare for installation
