Lights Out London - TOMORROW!

Remember that LIGHTS OUT LONDON is happening tomorrow.

To take part, simply turn off all of your lights tomorrow evening 9pm - 10pm!

This is what organisers Capital FM have to say:

Lights Out London aims to prove that we can all make a difference to the future of our planet. On Thursday 21st June - Midsummer's Night - we are inviting the whole of London to turn off all lights and non-essential appliances between 9 and 10pm.

As well as promoting long-term understanding of green issues among Londoners, this simple display of solidarity will show the world that we care. We can all make a difference - saving the world isn't just for superheroes!

Getting involved couldn't be simpler. Register now to show your support, then all you have to do is remember to turn off all your lights and non-essential appliances on Midsummer's Night. Remember to tell all your friends though - the more people that take part, the bigger difference we can make.

Even Picadilly Circus famous advertisements are shutting down - for the first time in 68 years!
