Control street, building, and vehicle light sources in CARLA. Switch groups on or off, adjust their color and brightness, and enable automatic nighttime lighting to prepare illuminated city scenes or blackouts.

Controls the map's light sources through the CARLA LightManager — turn street lamps, building/facade lights, vehicle lights or all of them on/off, set their colour and intensity, and toggle the automatic lights-at-night cycle. Use when the user asks to "turn on the street lights", "light up the city at night", "turn off building lights", "change the street-light colour", or "make lights come on automatically at night". Distinct from hiding lamp meshes (toggle-env-objects) and the sun (set-weather).

Paths.
scripts/…andreferences/…below are relative to the directory holding this SKILL.md. Your working directory is the user's project, not that directory, so prefix them with its absolute path or the command is not found.
Switch and tune the world's illumination — street lamps, building lights, vehicle
lights — via the LightManager. These are actual light sources (they cast
light): different from toggle-env-objects (which hides the lamp geometry) and
set-weather (the sun). Effects show on a rendered server.
Progress:
- [ ] Step 1: Check prerequisites (bash scripts/check_env.sh), clear FAILs
- [ ] Step 2: list a group to see counts/states
- [ ] Step 3: on / off / set a group, or toggle the day-night cycle
Commands need CARLA_HOST/CARLA_PORT from scripts/env.sh.
bash scripts/check_env.sh
source scripts/env.sh
python3 scripts/lights.py list --group street # counts + a sample
# light up the streets, warm colour
python3 scripts/lights.py on --group street --color 255,220,150 --intensity 2000
# turn building lights on for a night-city look
python3 scripts/lights.py on --group building
# turn everything off
python3 scripts/lights.py off --group all
# recolour without toggling
python3 scripts/lights.py set --group street --color 150,200,255
# let lights switch on/off automatically with the sun
python3 scripts/lights.py day-night on
Groups: street, building, vehicle, other, all.
Example 1: night city
User says: "make it a lit-up city at night"
Set night with set-weather (sun_altitude_angle negative), then
on --group street and on --group building.
Example 2: blackout
User says: "kill all the lights"
off --group all.
Example 3: automatic dusk lighting
User says: "have the street lights come on by themselves at dusk"
day-night on.
Problem: no visible change
Cause: headless -nullrhi server (no rendering), or it's daytime so lights wash out.
Solution: use a rendered server; set night (set-weather) to see them clearly.
Problem: list shows 0 lights
Cause: this map has few/no light sources of that group, or wrong group.
Solution: try --group all; some maps have sparse building lights.
Problem: lights won't stay on
Cause: the day-night cycle is auto-switching them.
Solution: day-night off, then set them manually.
Illumination state on the server (on/off, colour, intensity, auto-cycle). No file.
list reports per-group counts and a sample.
