So just recently I was driving on the expressway doing around 75 & hit a small bump and at that speed it felt like a big one. It wasn't that big of a deal but when I looked at my display that shows your mpg & oil life I could not see it at all it was completely dim. When the sunlight hits it I can barley see what it says, has anyone else had this problem & how do I fix this?

The car is a 1998 Grand Prix Gtp 4 door with 119k on it.
