voltage modules,... 5.0v 3.3v and 2.5v

Hi, I made some 'voltage modules' to plug into a breadboard. As you can see the input voltage 9volts is the black and red leeds on the left,
the regulated voltage 5.0 3.3 2.5 ~ et al is on the right side now on the breadboard I send the 9volts through the left rails and the right side has the voltage I want . See!
