Working Trailers Brake Lights for GTA San Andreas

This script uses the taillights of trailers. They completely copy the condition of the tractor's taillights.
Trailer lights react to:
– Tractor brake light;
– Auto-switching of the status of the headlights day/night of the tractor;
– Turning off the tractor headlights by the player;
– Disconnected tractor;
– The tractor engine is turned off.
Besides it:
– Forcibly turns off non-existent trailer headlights;
– Trailers without any headlights are excluded: Luggage Trailer "A", Luggage Trailer "B", Tug Stairs Trailer, Farm Trailer, Utility Trailer;
– Works both on CJ cars and on NPC drivers;
– With all the functionality, two or more trailers attached to the tractor are supported.
