School me on light systems. This thing has headlights/tail lights (should be on all the time) as well as brake, directionals, and backup that used to operate in accordance with what the vehicle was doing. Before the old esc died they all worked.
Now we just have headlights, and the backups come on once in a while with steering input and the directional kinda work one direction. All the wiring etc is in good order and worked pre new esc. Do some esc's not work with light systems or? Cant imagine it's a radio setting.

I hate lights.. kid loves them... ugh.
