You may want to use the dashboard's variable tab to see whether the variable is being set on the robot, and you are having issues with the DB, or whether the robot is having issues setting the variable the way you expect.

To summarize what I'd check in your code. Verify that the limit switch code is setting the SD variable when you expect. Make sure it is in teleOp or a loop and is executing repeatedly. Then I'd probably just place the LED in the Custom tab and delete the diagram read code that updates the LED.
