I really like the design of the 8 interior, I think it's aged nicely, and I especially like the dash cluster, but... It's too dark in there at night. Modern cars with their ambient/down lighting really do make it a much nicer experience at night, so I had a go and recreating this on a basic levels. The LEDs are leftovers from my last 3 series, so it's actually a BMW colour, but seems to go nicely.
It's 2 LEDs set into the light housings front and rear and wired to the ignition using the wiring already going to the front interior light. As long as the light in the ceiling isn't distracting as a driver, I'm happy with it (usually they're recessed to hide the light source, but there isn't space to do that easily in the sunroof interior light, so I had to use the original bulb housing, hence the reflection of light).
Without lights
And with lights
It's a little dimmer in person, but it's only a phone, so not the best photos. It was at least exposure locked between shots.
