I just discovered the LED lighting aisle in our local Auto Zone. Wow. These things have really come down in price. I purchased a long flat strip of the blue LED tape lights several years ago from one of the popular avionics suppliers. I don't remember the exact cost, but I remember thinking they were very expensive, but really cool... so what the heck!
Auto Zone has got a wide variety of strips and individual LED lights for between $15 and $20. I'm going to install 12" of white tape lights in both my baggage compartment and below the canopy longeron on the right side of my cockpit for nighttime loading/unloading. I bought the 2 12" strips in a single package for ~$18.
Very cool.
