Displays here switch on around sunset. In Wheaton that means about 4:46 PM in early December and 4:47 PM by mid-month — the earliest sunsets of the year fall right in the middle of lights season. It is properly dark by about 5:17 PM, which is when the displays look their best. December nights in Wheaton typically drop to around 30°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 Wheaton cluster, OpenStreetMap maps 0 public car parks and 10 public toilets. There is no shortage of cafés and takeaways for a hot drink on the way round.
Brookside Gardens turns its Wheaton grounds into a walk-through evening light display running from late November into early January. Tickets cost $10 for ages five and up, with younger children free.
