This Light My Bricks LEGO lighting kit includes everything you need to add lights to your LEGO 42145 set. This lighting kit features 13 individual LEDs, including red, green and flashing white LED bit lights, to authentically recreate the legendary rescue helicopter's rear wing lighting system when rescue conditions are at their darkest. This entire lighting kit is powered by your existing powered-up battery box thanks to the Light My Bricks powered-up cable. Watch the rotor blades of the Airbus helicopter spin freely without any cable interference. If you prefer to power the search and rescue lights independently, you can easily do so with the included USB cable. Light my Bricks offer LEGO fans an easy way to add LED lights to their LEGO models. All components in the Light my Bricks sets are plug-and-play - no electronics knowledge is required for installation. Light my Bricks parts are small and delicate enough to fit between and under LEGO bricks. 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 light up.
