@Chistian
Lightbar is on LoneWolfie's page, and the car is the Koenisegg CCX by SentryGunMan (SGM)

Which car, which name of lightbar?

@ dominicyarnell oops my mistake it's actually Driver SF Police Props.

@dominicyarnell it's in the description but i'll tell you again anyway:
1. SF Police Props by LoneWolfie
2. Koenisegg CCX by SentryGunMan(SGM)
that's it the police skin comes with the car itself and theres another lightbar that also comes with the car but it may look more park of the car but I like LoneWolfie's better. Check out my Koenisegg CCX Police Car V3 if you want it with the lightbar that comes with the car that i've added flashing lights onto in my workshop files!

what is required?

@Anator ok so it's the Driver SF Police Props by LoneWolfie

@Anator ok

i have th car i did mean the light bar =D tnx

the lights themselves are part of gmod but the car and lightbar isn't. do you mean the lightbar? cuz that's made by lonewolfie i'll put a link in the description in a little bit

how do i get the addon or whatever i need to make the lights not an error
