You may like to keep a boolean state for each LED, then the code becomes even simpler...

if (digitalRead (redled2Pin) == LOW)
     digitalWrite (redled2Pin, HIGH);
  else
     digitalWrite (redled2Pin, LOW);

BECOMES

{global - up top}
bool redState;

{local - to your function}
  redState = !redState;
  digitalWrite (redled2Pin, redState);
