Bio I am a 71-year-old Lego builder located in the States, I build kits, MOCs, and I customize. I build covered bridges, trestles, diesel and steam locomotives. BIG BEN I built the Big Ben kit first, and added my own custom lighting (using elements I purchased from Light My Bricks and the Light My Bricks sound kit later. Lighting Kit Light My Bricks produces an excellent lighting kit, the connecting wires and wires with lights have the appropriate miniature connectors attached, and are packaged/sealed in their own clearly marked packaging which indicates the length of wire in cm. The box has nice padding and is sealed on one end using a magnetic strip. This makes it extremely easy to access the product and store the product as you build. Sound Kit The elements in this kit are as shown on the Light My Bricks Website. I installed this sound kit in the base of the Big Ben clock. I went into iTunes, bought a sound recording for the Big Ben clock, converted the recording to MP3, and loaded the MP3 sound into the chip. Conclusion I have bought several additional light and sound kits to install on a number of Legos that I have already built. The engineering, quality, pricing, and customer service of the Light My Bricks kits are, in my opinion, EXCELLENT. The installation instructions are on the Light My Brick website and if you have a question, just email them, these folks are very responsive and extremely helpful. Cheers!
