I asked tps. He said it's carbon wrapped and not carbon fibre. It also is the shape that looks like a clean shell from the back. But I'll probably end up getting the tps if I can't find this one that looks cleanerThe phone is the one I sold sometime back.. don't remember where I got it from.. but I think TPS shop makes them now
They get dimmer when you turn the headlights on. However, I never dim my gauges so I have no idea if they are on that dimmer circuit as well. I drove the Mercedes today so when I get home tonight if I remember I will try turning that dimmer wheel see if it does anything. I do know for sure that they are bright in the daytime when the headlights are off and they go to a dimmer setting when the headlights go on.Are those gauges on the same dimmer switch as the gauge cluster?
