In cases where you do need an outside light for safety, please make sure you point them at the ground where you need the light and not upwards into the sky!
LED ones have less environmental impact (and will be much cheaper to run) and please, please avoid those ghastly 500W ones with the glass tube-shaped bulbs.
For movement activated lights, please take time to adjust them so that humans trigger them but not small animals.
All simple stuff which will limit the damage.
