This Light My Bricks LEGO lighting kit contains everything you need to add lights to your LEGO 75308 set. The Light My Bricks LEGO Star Wars R2-D2 Light Kit has a total of 13 individual LEDs, including two unprecedented color-changing LED bit lights. Also included are two specially designed Sparkle effect boards. These were specially designed by Light my Bricks to mimic the R2's logical function display. Speaking of special effects, for all the Lucasfilm super fans out there, Light my Bricks has included remote control and sound effects in this kit in addition to the lights. With the remote control also included, you will feel like you are on the movie set when R2-D2 starts beeping and glowing over your communication via remote control. You can also purchase a smaller and cheaper Light my Bricks light set, which only includes the light effects (without sound and remote control). With detailed step-by-step instructions (picture by picture instructions with little English text), anyone can add LEDs to their existing LEGO set to make it glow.
