LAPD Ford Police Car Not Spawning and Lights not Working

[forter4]

Hi, I tried installing the following mod:
https://www.gta5-mods.com/vehicles/lapd-cvpi-with-code-3-defender

After installing it, I notice that they don't spawn when I'm being chased nor do the lights on top of the car work

Anyone know what went wrong? I installed it exactly as instructed

@forter4 first off, which car did you replace?
