I am happy about this mod, during daytime you can see your emergency lights better, and at night you can clearly see the improvements. It looks more realistic and creates a more entertaining atmosphere.
The only problem I encountered were the indicator lights that were always on, this occured on every car, even those that are parked and with their engines off, . When rolling code 2 or code 3 the taillights of the cruiser didn't flash anymore. The author noticed this problem and after reading the readme I was capable of solving this problem. It was very easy to fix. This mod is a must-have and I recommend it to everyone!
