READ BEFORE ORDERING
THIS BUILD.
THE IMPORTANT DETAILS.
- 2 Dock housings need new Tether attachment locations. Check the stud footprint, housing clearance and access to both Belt sockets at each original board location before buying.
- At least one 12-port board is split into a Dock 9 and Dock 3. Check room for both, leave a Belt connection between them, and keep the original light groups together where possible.
- Check opening doors, steering and removable panels with the model unpowered. Secure loose Belts away from wheels and hinges; this proposal does not establish clearance during motion.
- Capacity allowance: 8 Astro light/string connectors across 12 Dock Astro ports. This checks total capacity only. Assign lights by their actual locations and confirm each Dock’s local capacity and lead reach before buying.
- This is an independently derived component plan, not a physically tested installation or a replacement step-by-step instruction manual. Use the original guide together with the concordance and changed mounting/power plan.
Connection counts are a planning check. They do not verify local grouping, cable reach, power draw or physical fit. Astro ports and Belt sockets are different connections.
How the cable allowance was calculated
2 network components require at least 1 Belt links in this planning allowance. Original cable lengths are retained where mapped; included FX Belts are credited once. Extra links use 50 cm Belts as an unmeasured routing allowance. Check the actual branch and effect grouping against every source step.
THE CONCORDANCE
EVERY CHANGE.
IN PLAIN SIGHT.
Quantities below are individual components. The shopping list combines shared packs, then rounds up once.
| Original 1.0 item | Proposed 2.0 replacement | What to check |
|---|---|---|
| 8 x White Bit Lights (15cm) | 8 × Astro Light Regular - White 15cm ↗ | Keep one light at each original fixture. Route the flat lead without pinching it and confirm that its 15 cm lead reaches the chosen Dock. |
| 1 x 12 Port Expansion board | 1 × Dock 9 ↗ 1 × Dock 3 ↗ | Astro ports are separate from the two Belt sockets. A 12-port board becomes Dock 9 + Dock 3, requiring two attachment locations and a linking Belt. |
| 1 x Round Battery Pack (requires two CR2032 batteries) | No separate purchase | Power changes to a 60 cm USB Flux Belt and separately purchased manufacturer-specified 5V/2.4A supply. Old battery/USB alternatives are not added twice. |
| Additional 2.0 links | 1 × Belt 50cm ↗ | 2 power-network components need at least 1 links. 0 source-length Belts plus 0 Belts included with FX controllers leave 1 additional links. 50 cm is a conservative routing allowance, not a measured installation length. |
| 2.0 USB power entry | 1 × Flux Belt 60cm ↗ | One Flux Belt per retained power group (old AA/USB alternatives combined). USB adapter or power bank excluded. Multiple sources must feed electrically separate networks; never join powered outputs. |

THE EXTRA
LEGO PIECES.
The lighting cart excludes the LEGO set and all extra LEGO pieces. These are the pieces listed in the original guide; adapting 2.0 mounting may require additional pieces.
The original guide does not provide a separate extra LEGO inventory. Inspect every installation step before ordering. This does not establish that no extra pieces are needed.
Match shape, size and colour against the original guide. Element IDs are omitted where the source does not identify them. Docks and Meteors include the Tethers stated on their product listings.
PACK-AWARE PARTS
CHECK IT.
THEN BUILD YOUR CART.
Enter individual compatible 2.0 components you already own. A pack can contain multiple lights, strings or Belts. Included FX controller Belts are deducted automatically; if you own an FX controller, enter any separate Belts you own as well.
