The BLIGHT (Binary light controller) filetype controls lighting effects on characters, karts, items and objects in a track. It is always seen in the "./posteffect" folder inside an SZS. This file is not required for a track to load, as there is a default.blight file inside Common.szs.

However, one thing to note is that although 16 lights are stored in this file, only 8 can be referenced by the KCL (IDs 00 to 07). This is because the KCL only has three binary digits to reference lights (and 111 in binary = 7).
Light Object data (LOBJ)
The first object starts at 0x28. These addresses are relative to the start of the object.
| Offset | Size | Description | Extra Information |

| 0x00 | 0x04 | "LOBJ" magic | (always 4C 4F 42 4A, LOBJ in ASCII) |

| 0x12 | 0x01 | Unknown | Always 00 on unused/undefined lights, 02 most common, 01 (CCW) and 04 (RR, TD) seen. |
| 0x13 | 0x01 | Unknown value | Always 01 |
| 0x14 | 0x02 | Light ID | The ID used here is referenced in KCL files, and also matches the ambient lights at the end of the BLIGHT. |
| 0x16 | 0x02 | Unknown value | (always 06 41 or 06 21) |

| 0x48 | 0x08 | Padding? | (always 00 00 00 00 00 00 00 00, unless it is the last light. In that case, it's 00 00 00 FF 00 00 00 00) |

Ambient Light data
At 0x0528 in the file, a list of colors starts, separated by four 00's. These are the ambient colors used by each light. They're in order, and their IDs are from 00 to 0F (matches the main lights above).
| Offset | Size | Information |
|---|---|---|
| 0x00 | 0x04 | RGBA Ambient Light Color |
| 0x04 | 0x04 | Padding |
| 0x08 | End of color, start of next | |
Just like light objects, there are 16 ambient colors. All unused ones are 64 64 64 FF (a neutral gray).
Known BLIGHT files
