Hello LCPDFR. This is my first post :)

I'm using come squad cars that have els lights. I want to be able to select what siren I want to use but whenever I try and select it it just automatically jumps to Manu which I'm guessing means manual. Am I doing something wrong or is this how its supposed to work.

This is because you have the horn and the ELS siren assigned to the same keys. Try changing the horn to a free key and keeping the ELS toggle siren key at G. I assigned the horn in my game to X while keeping the siren toggle key at G. Hope this helps.
