Welcome! To adjust the brightness, scroll through the options with the left button on the dash until you get to one that shows 1-5 with increasing number of lines between them. Then use the right button on the dash to change. I found that even at lowest brightness it was still way too bright at night so I put a layer of 20% window tint over the whole cluster. That took the sharp glare off it at night and is tolerable now. Any more tint than that makes it hard to see in the daytime.
