You can use ImpulseTactics and Rich's Police Enhancements at same time (Patreon)

For ppl asking what's better

These are two different Plugins with different code logic

My pit code and TVI will not conflict with each other as the both use different methods

I use both in my game. Inside RPE ini you only need to leave EnableTrafficLightControl=false

My signal manger uses green and yellow Opticom that's why yo need to leave TrafficLightControl to false

everything else you can set to true if you like

Riches plugin has a lot of cool shit my personal fav Ambient Backup
