    20190820_205737.jpg I have a 2015 VNL780. I was just driving my and speedometer and RPM cluster started flickering and then just shut off (see picture). Is there a bulb that I need to replace in the instrument cluster? Everything works but the light for those two gauges. So far I tried removing and plugging back in the light dimmer and it didnt help.

    Any ideas would be much appreciated.

    Not yet, just looked at some videos on how to remove the gauge cluster to get to those bulbs. when looking at some videos I didn't see any bulbs on the circuit boards... I'll have to look at it later this week once I'm done with this trip. I can still see the speed and rpms just not used to it without the back light.

    You won't see the bulbs in a video.

    These are the sockets as I know them. Volvo may very well have changed systems.

    Make sure those are the sockets you need. I was just giving you an idea of what to do look for.

    Ok, will do. I'll give my volvo dealership a call and ask to make sure that's what I have.
