Speedometer backlight

I have the white BD speedometer, but my back light has burnt out making it difficult to see how fast I'm going at night. Is there a bulb in there that can be replaced? I pulled it apart to a point, but when I got to the circuit board on the back, I stopped cause I didn't see a way to get any deeper into it.
 
If you do it anytime soon, snap a few pics so I know how the hell to get it apart. I got to where the computer board is on the back of the white case, but I only seen I think 1 Allen head screw, but that didn't look like it would take it apart. Got lost and wasn't sure what to do, so I just put it back together lol
