I checked through the first few pages of the Forum and could not find anything that talked about this problem with RC2. The AI Cop car lights are not working. The Sirens work and the will join pursuits and come to callouts but they will not come with lights on. They have the normal problem I have read with ELS in which one or two are on but they are not running. Any thoughts?

if u run els u need to enable aI support in the settings

I would leave them turned off, way more crashes and lagging with AI ELS turned on.

Okay. If it crashes then I won't. What file would I change it in in case I wanted to try?

Open the ELS.ini in your GTA folder, and change AI ELS from 0 to 1

use els v5 it wont crash

Okay thank you. I will give it a try and see what happens.

use els v5 it wont crash

Not necessarily true, for some, it is the opposite way round and will crash less when using V6.
