Turning on beacon lights (as mechanic) will also send player surrenders to chat

That happens only if you enter job vehicle as civilian trough.

rather annoying though as it happens to mechanics also

Well yeah, but tehnically you can also get wanted stars while playing as mechanic, so I am not sure if removing it would be a good thing.
Maybe it should only appear once you actually have wanted stars.

or make mechanics as a public service like the fire dept and paramedics xD

I can confirm this happens even if you are a mechanic and have no wanted level stars

Holding N will now toggle lights after 250ms and surrender after 1000ms.
