ELS Lighting Suggestion

Hello, 

I wanted to make a suggestion to the vehicle builders out there when building an ELS lightbar. I would try to do this, but I have a pretty good feeling I would not do a good job or most likely I would mess it up. 

One of the features I have not yet seen on ELS equipped police cars is a three stage lighting feature where the following would happen:

Stage1:

Amber warning lights and rear emergency lighting turns on

Stage2:

Now just the rear of the lightbar turns on but the front of the bar stays off. all front body lights would also stay off.

Stage3:

Christmas tree lol. All lights turn on. 

I know a lot of agencies here near the Greater Toronto Area have the ability to do this for two generic reasons. 

1) they can turn on stage 2 when assisting an officer on a traffic stop to not disorient or blind the officer in front with front flashing lights. 

2) If they are the primary on a traffic stop, then can perform the stop with stage 3, then go to stage 2 in order to not expose occupants of the car to possible medical issues like a seizure. 

If I missed a model out there like this, please let me know. It is something I havent come across yet so thought I would put my two cents in on it. 

I can do repaints and textures like crazy, but still struggle with models and CAD work
