Lumibricks Interstellar Drive-In L9104 Review: 2,188 Pieces and 13 LED Lights

Lumibricks’ Interstellar Drive-In L9104 makes its strongest impression after dark. Its 13 LED lights and two light strips bring a circular, retro-style diner and a flying saucer to life, while a pink four-seat convertible gives the scene a playful roadside stop. The 2,188-piece set belongs to the Road Trip series and builds into a display with plenty to inspect beyond its neon centerpiece.

The set was provided by Lumibricks for review. It’s rated 16+, measures approximately 12.6 × 9.84 × 8.86 inches, and includes four Lumibricks-style minifigures and 26 specialized printed elements, with no stickers. The listed retail price is $119.99 USD, $163.00 CAD or 133 EUR. More set information is available from Lumibricks.

Box contents and lighting

The sturdy box has graphics on both its front and back. This copy bears a manufacture date of Sept 04, 2025. Inside are the build parts, an orange box holding the light kit, and two substantial instruction manuals: one has 256 pages for steps 1–7, and the other has 148 pages for steps 8–12. Digital PDF instructions can also be viewed or downloaded from the Lumibricks website.

The lighting kit includes elements for the diner and saucer, plus a small CR2032 battery case for the car and a white case for three AAA batteries. Batteries are not included. The kit also provides a USB cable, which can connect to a 3A to 5A power source; the listed power options include standalone battery cases, USB with a battery case, or USB with a portable power bank. Tweezers and a brick separator are supplied, too.

Numbered bags correspond to the 12 build steps, with three additional bags for the baseplates, minifigures and specialized pieces. There are 38 bags altogether, so the step-by-step sorting should help keep a large build manageable.

Build notes: diner, car and saucer

The opening step assembles the covered drive-through. The convertible follows, with working headlights and taillights and room for four. Its rear wings are a less convincing design choice; a brick-built tail fin might have suited the car better.

The diner’s black-and-white tiled floor establishes the retro look. Interior work adds red counter stools, a table, cabinets with small accessories including a rubber duck, camera and mug, and a magazine rack made from printed pieces. A curved wall wraps around the room as the first diner lights go in. Later steps add more seating and a jukebox.

One practical limitation appears in the seating: the rounded bottoms of the included minifigures prevent them from fitting properly in all the diner seats. The diner opens at the center, which improves access to its detailed interior and adds play options.

The roof takes shape across steps 8 and 9, with further lighting integrated before it’s attached. The reviewer encountered no alignment trouble, though other builders had reported fit issues they suspected were caused by misplaced underside roof pieces. Careful placement during those steps may help avoid a frustrating fit at assembly.

The saucer begins in step 10, and testing its lights before finishing the build gives an early preview of the set’s main visual draw. Purple and blue LEDs produce a vivid glow. Steps 11 and 12 finish the scene with planter boxes, flowers, a serving cart and two robots.

Display appeal and caveats

Four distinct minifigures are included: three appear dressed as diner staff, while the figure in a pink suit is presented as the car’s owner and a customer. The styling may not suit every builder, and the saucer itself has no seating or alien figure inside; adding either would have made the sci-fi vignette more interactive.

As a finished display, L9104 has a clear identity: glowing retro roadside diner, colorful lighting and a saucer perched overhead. It can stand alone or join another Road Trip series build, such as the Twilight Motel. For builders drawn to sci-fi scenes, the lighting and dense interior detail carry the set; the seating fit and roof alignment reports are the points to keep in mind during assembly.
