This is the core of the lighting system. I didn't really feel like imbedding several LEDs or custom creating a LED color mixer. With my modding background this was the no brainier choice. Using a set of pliers carefully crush the plastic housing. Cut the wire and slip the LED out of the housing. Using some phone wire to extend the length.

Fish the led threw the frame of the deck. If you extend the led wire don't attach it to the plug end of the wire until you fish the wire threw the deck. Use some hot glue to mount the led in place.

Wire the led into the controller and light it up. Make sure the mixing controls fully work and that you can get all colors.

Next up is the tile modifications for the sensors. Using a 1/4th inch drill bit drill 3/8 of the way threw the tile in each corner of each tile. Do not go all the way through! If you have access to a drill press with a stop on it will make this allot easier.

Install the spring into the hole by just sliding it in. use a gob of super glue to cover the entire first spring loop at the bottom of the hole.

Using some of the foamies. Cut a strip 3/4" wide and then cut 2" lengths. Remove the adhesive backing and stick it to the deck 1/2 inch away from the spring. Do this to only 2 sides of the tiles.

Using some of the aluminum tape cut a 3/4" strip 2 3/4" long. Stick it over the foamies and 1/4 overlap onto the tile.

Run a wire between the 2 tabs of aluminum tape and adhere it together with some extra foamies. At the same time on one side place a 6" leader to connect to the terminals under the deck. Use a little super glue to hold the wire down to the deck and to hold the extra foamies peace to the deck.

Here is the lead to the sensor contact. The total gap between the sensor contact and the deck rail should be 1/16th of an inch. If its to narrow you can use a wide flat head screwdriver to compress the spring a little, as well as some pliers to pull and extend it. The foamies also provides some dampening to the step making it more comfortable to use.

With the tiles installed and hooked up we decided to do a quick test of the lighting system to celebrate the build being all done!
