Hi Jennifer,
Thank you for your review. During winter our solar lights can’t absorb as much direct sunlight as it's cloudier and the sun isn't as strong. So our lights will still work in winter but their brightness levels will be reduced. Is your light in the sunniest place possible in your garden?
Once it gets to spring/summer you will notice the light get brighter. If it doesn’t though please don’t hesitate to get in touch with our customer service team, we’re always happy to help.
Sam :)
