Solar powered decorative string lights with colour-changing bulbs that are ideal for decorating shrubs, trellis, parasols and doorways. Powered by a separate solar panel, these colour change party lights can be placed in shady areas if required as long as the solar panel is placed with maximum exposure to light. This string of \'festoon\' style lights will automatically illuminate when it becomes dark, giving up to 6hrs of colour morphing light during summer months. With no mains wiring, and no operating costs these colour change solar lights are simple to install and ready to enjoy! Please note that the colour change effect is synced so that each bulb changes colour at the same time, so that you will see all bulbs showing, red, then blue, then green for example at the same time.

Leave the switch in the off position for two sunny days to ensure the battery is fully charged. Once fully charged switch to "ON" and your light will come on automatically at night. Rechargeable batteries become less efficient with repeated charge-discharge cycles and the battery capacity reduces. If you find that the battery appears to be less efficient or does not run for long we first suggest you try to boost charge it. Leave in the off position for three to five sunny days to allow the maximum charge to the battery. If after this boost charge your battery still does not perform to expectations you should replace it. Do not position under bright light as this will prevent the light switching on at night.
