1) “The Great Christmas Lights Fight” opener (shown here), 8-10 p.m., ABC. For six hours (over three Mondays), we’ll see supersized holiday displays. Each hour has four homes, with one chosen as the winner. Tonight has a piano and a mini-golf course, both playable, and a ride through Lollipop Land. One display sprawls over a 90-acre farm; another (on a mere four acres) glows with 250,000 lights.
2) “Pitch Perfect: Bumper in Berlin” debut, 10 p.m., NBC. Before this debuts Wednesday on Peacock, here’s the opening episode. Adam Devine returns to his “Pitch Perfect” movie role as Bumper, high on ego, low on talent, struggling as a security guard who sometimes assembles his a cappella group. Then he’s told he could be a star in Germany. The result is fun, when it doesn’t go too far in burying Bumper; Sarah Hyland is excellent as another U.S. transplant.
3) “The Voice,” 8-10 p.m., NBC. Leading into “Bumper,” things are getting serious here. Tonight, the top 10 perform and viewers vote; on Tuesday, two will be ousted. Next week, the top eight will be trimmed to a final four for the finale.
4) “The Cleaning Lady,” 9:02 p.m., Fox. Life keeps getting worse for Thony. Now a drug deal has gone bad, leading to a wild chase and an international adventure. Meanwhile, Arman was startled to learn his wife married the evil Kamdar … and never really divorced him. That follows the mid-season finale of “9-1-1,” with the Santa Ana winds seeming to stir strange evemts: A young-woman sleep-drives into the station; a family dog finds a hand.
5) “Whitstable Pearl” season-opener, any time, www.acorn.tv. It’s the second season of this show, with Pearl (Kerry Godiman) solving cases while running her restaurant in seaside England. She’s helped by her mom, her son (Rohan Nedd, the “Harry Wild” co-star) and a local cop she used to date. There will be two episodes each week, through Dec. 12, starting with a fairly good one that takes advantage of the British bunkers that were ready for any invasion.
