this is what they should be like
I just created a post similar to yours.
They go on and off for certain cars at time. However, mostly during rain races all cars will have their headlights off and brake (rear parking) lights on. Your car’s dash will be lit up, but no headlights outside.
Also, I do agree with many here that headlights simply aren’t bright enough during night races. The light needs to practically bounce off the tarmac like it did in FM6.
This is certainly not an Xbox X versus regular Xbox issue or anything to do with hard resetting. I wish the developers would be quick to fix this. It’s been there since launch!
