When to go
Displays here switch on around sunset. In Rowlett that means about 5:20 PM in early December and 5:21 PM by mid-month — the earliest sunsets of the year fall right in the middle of lights season. It is properly dark by about 5:49 PM, which is when the displays look their best. December nights in Rowlett typically drop to around 32°F.
Twenty-nine homes here mount displays ranging from modest to elaborate, several synchronized to music you can tune in from your car; the group posts a neighborhood map on its Facebook page.
