Lightailing instructions: finding and following the install guide for your kit

Where the guides live

Lightailing's homepage FAQ says detailed manuals and tutorial videos are provided and that PDF instructions can be viewed on its Instruction page at lightailing.com/pages/instruction, which the site menu also links as Installation Guides. [6] Its Light Kit Installation Tips and User Guide page adds that model-specific instructions are in the PDF guide or video tutorial for your kit, when one is available. [5]

The FAQ points to the same Installation Guides page and says many kits have video tutorials, but not all of them, so a PDF may be the only guide for some sets. [1] The terms of service list installation guides and instructions among the content Lightailing owns or licenses, which is a reminder that the official copies are the ones on its own site. [3]

The homepage FAQ adds a second route to videos: it says installation videos exist for most light kits and can be found by searching the set number on the Lightailing YouTube channel (@Lightailing) or the BriksMax channel (@briksmax9383), and to email [email protected] if you cannot find yours. [6]

Match the guide to your set and kit version

Three details decide which guide is yours: the LEGO set number, the brand and the edition. The FAQ says to find kits by LEGO set number and does not recommend using a kit on a different set. [1] It also says Lightailing and BriksMax kits for the same set can differ in lighting design, components, installation method and overall effect, and that some kits come in upgraded editions such as BriksMax 2.0, remote control, RGB, wave sensor or sound remote. [1] A BriksMax guide for your set will not necessarily match a Lightailing kit for the same set, and a remote edition may route power differently from a standard one.

Take the set number from the LEGO box or instruction booklet and the kit name from your order confirmation or the product page you bought from. The refund policy asks buyers to check the set name, set number, kit version and any variant or control option before ordering, which is the same information you need to choose the right guide. [2] If two guides look close, compare the photos in the guide with the parts in your box: bag labels, the number of light strips and the type of power unit should line up.

• LEGO set name and number, from the box or booklet.
• Brand: Lightailing or BriksMax. [1]
• Edition: standard, BriksMax 2.0, remote, RGB, wave sensor or sound. [1]
• Power: USB, battery box or both, as listed for your kit. [1]

Lightailing's own tips for cables, boards and lights

Lightailing's Tips to use Light Kit Component page gives four handling notes. Hide wires in the gaps between bricks so the build still looks like LEGO. Take extra care when plugging a cable into an LED light, because the light has tiny components, and do not press hard on the port or the light. Route the cable to the expansion board and seat it properly, checking that the board's slots are straight and correcting them with a tool if they are not. And when a light sits under a brick, the yellow section of the light is the top side. [4]

The Light Kit Installation Tips and User Guide page adds a before-you-begin routine: check all kit components, review your installation guide, handle wires and LEDs carefully, and test the lights before installation. For connections it says to check connector orientation before inserting, not to force a connector, to make sure every connection is secure before powering on, and to disconnect power before adjusting or reconnecting anything. For wiring it says to route wires between studs, avoid pinching them, tuck away excess wire and position LEDs as the guide shows. [5] It also says model-specific steps are in the PDF or video for your kit, when one is available. [5]

The FAQ adds that the kits are designed for finished sets and need no drilling, cutting or special tools, and that if a connector does not fit you should not force it but check the guide or contact support. [1] Forcing matters for more than the part: the refund policy says exchanges are generally not available for damage caused by incorrect installation or misuse. [2]

Power: what the FAQ allows

Lightailing's FAQ says power depends on the kit: USB, a battery box, or both. Batteries for a battery box are not included. It warns against an incompatible or higher-voltage adapter and suggests contacting support if you are unsure, and it says the kits are for indoor use only and are not waterproof. [1] The homepage FAQ is more specific: some kits come with a battery box and a USB port for dual power, others support USB only, and the power supply should be within 5V 2.1A. [6] The refund policy lists an unsuitable or incompatible power source among the causes of damage that are generally not covered by an exchange, so use the power option your kit's product page or guide names. [2]

A practical order of work, drawn from these pages: check every component against the guide, connect the lights to the expansion board and test them with the supplied power option before you close up the model, then route wires between studs and reassemble. The user guide lists testing before installation as a first step. [5] Testing first also means a dead light can be reported with a short video, which the refund policy asks for, before any rebuilding hides the problem. [2]

The user guide page also lists safety points: use only a power source that meets the kit specification, and disconnect power straight away if you see overheating, damaged wiring or other signs of an electrical problem. [5]

If a guide is missing or the kit misbehaves

If you cannot find a guide for your set, contact support before you start rather than guessing from a neighbouring set. The FAQ lists [email protected] and on-site chat, with a target reply within 24 hours on business days, and asks for your order number, the LEGO set or product name and photos or video. [1] If lights do not come on or flicker, the user guide page suggests quick checks: confirm the power source meets the kit specification and connectors are secure, look for damaged wires or loose plugs on the lights that are out, check the remote battery and pairing steps on remote kits, and suspect a loose connection or unstable power source if lights flicker. [5] For more detail, work through our light kit troubleshooting guide; quality problems must be raised within 30 days of delivery under the refund policy, and the two-year warranty covers eligible products after that. [2]

• Order number and the email address used to order. [2]
• LEGO set name and number, and the kit's full product name. [2]
