Yes I have....there are many reasons why driving LED's with constant current, PWM etc. is better than variable voltage sources but in this case, it is just to plain simple and inexpensive to bother with the textbook correct way to do it.
Cheap and it works just fine!!
PS: Don't get snookered into buying those overpriced LED strips that are being sold out there....The inexpensive <$10 models that you can get at your local Walmart or Autozone work just fine in an airplane.......
