ok guys so i have an issue with my s2000.....hopefully its something minor and someone on here can help me out,shortly after washing my car i noticed my rpm gauge was extremely dim (still working though)compared to how it use to be,the temp,speed gauges are all fine,any ideas on what the problem could be(fuse,bulbs etc) i dont think u can adjust the brightness of the lights from the gauges can u,could it be possible that i accidently set the brightness low somehow or is it just an electrical issue...any help would be appreciated

 

The gauge has + and - buttons to adjust the brightness. Holding down the + button for a few seconds sets it in high brightness mode. Try that but I cant see how washing the car would alter that setting. Other than that I'd check the battery contacts for corrosion, etc.

 

as CapoArgentino said
there is a way to set the brightness and its the bottom left on the dash
