Displays here switch on around sunset. In Federal Heights that means about 4:36 PM in early December and 4:36 PM by mid-month — the earliest sunsets of the year fall right in the middle of lights season. It is properly dark by about 5:07 PM, which is when the displays look their best. December nights in Federal Heights typically drop to around 18°F.

Practicalities
Residential displays have no facilities of their own — no parking, no toilets, nowhere to warm up — so it is worth knowing what is around. Within about three miles of the Federal Heights cluster, OpenStreetMap maps 8 public car parks and 5 public toilets. There is no shortage of cafés and takeaways for a hot drink on the way round.
