It’s very bright out of the box, but there are adjustments for everything.
Turn on the setting for less intense lights. Turn down the backbox to reduce glare on the glass. (Mine is at 15). The GI lights can be turned down, but I like them bright. The insert lights can be turned down, and so can the flashers.
I’m pretty sure that if you turned them all, all the way down the game would be black. So there’s no reason to complain in a home environment.
On route it will be set up to take your money, and ya, it can be blinding.
