Outdoor Lighting Perspectives does this. I am not certain how much lead-time they needed though.
I think those star shower laser lights might be an easy alternative to traditional lights. I've seen them on a few houses and they seem to be the right amount of color and light. I have only seen red & green though. Not sure if there are other colors. Not trying to take away from PLS in any way, just wanted to share an alternative.
Feel the night to light the place up this year and we are just too old this kind of job ourselves
Can anyone recommend a professional holiday light installer?? Preferably one that supplies the lights. Not a big job.
