The first step to getting awesome Halloween outdoor lighting is choosing the right colors. Blue, green and purple spot lights add the perfect spooky atmosphere for your front yard Halloween cemetery or yard haunt. And you can add orange and red lights as the accent colors since they contrast well with the blue and green. (They are opposites on the color wheel). Try to stay away from too much white light for Halloween as it tends to drown out the other colors which could add the spookiness factor.
If you don't already have a strip light in place, one of the best locations for it is roof eaves. Not only does it create a beautiful effect for everyday lighting, but it also provides the perfect spot to showcase Halloween decorations. Or turn your front door into a mysterious portal by fixing strip lights around the frame, or run them along skirting boards to cast a ghostly glow across the floor.
