As topic, let us put them on ourselves.
I’m been in certain online races where everyone around me headlamps in a night races were working except mines, and I’m like, you’ve got to be kidding me. Luckily for me I had the track lines on for guidance. They need to look into this for sure. We should have on/off access for all headlamps in online play imo.
Generally when that happens it’s the same for everyone. To all players in the race, it seems they are the only one without lights.
