Adding flashing lights (Red and Blue)

Hello, I am trying to add Red and Blue flashing lights like a Police car. I am going to make a Police car in 3DS Max, Could you help me out? The game is called City Life RPG, and you can do anything i mean anything, you can get a job (You get to actually do the job not just finish it in like 2 seconds) You make your life choices! Also the game is based on Australian. There’s ton more stuff to go into but don’t really wanna go into too much detail.

Thank’s in advanced!

The code to flash lights has been posted many times:

You may want to consider changing a texture rather than flashing a light depending on your platform and the number of point lights you have in the scene.
