You'll still have fun either way! I'll be sure of that. Each of the Police, Fire and EMS apparatuses will have options where you can activate and disable light modes. Main mode would be the Code 3 response, all lights are activated. With all of the lights on, it will probably affect your game frame rate depending on the condition of environment and severity of calls. If you're on a scene of an accident, or a minor call, while parked in a busy traffic lane or obstructing the flow of traffic, you can disable all lights but keep the rear on with traffic advisory stick on ( including rear brake strobes, rear dash red/blue LEDs, etc...). This will help maintain your frame rate high, and should not affect game play's performance. Or you can disable all of the emergency lights, and turn on the traffic advisory stick alone. It all falls down to your decisions and the capacity of your computer's gaming performance.
