LEGO® TARDIS Console Lighting Kit / Pulsating Reactor Core Kit
Update December 3, 2018: More will be in stock by next month.
We originally developed this kit for the LEGO® Doctor Who set (21304), but since developing it, we've had people use it for many setups that don't involve the Doctor! These make great reactor cores if you have a nuclear power plant, or weapons cores for alien laser batteries.
Assuming you DO use it for the Doctor Who set, it will transform your LEGO® TARDIS console into an animated representation of the original. The kit includes one replacement transparent blue console core with four Pico LEDs pre-installed, two replacement Technic axles, and one 4-port lighting effect controller with custom TARDIS animation sequence pre-loaded. NOTE: If you plan to use this kit for the TARDIS, the kit alsorequires the LEGO® set #21304 (LEGO Ideas Doctor Who).
Check out the video clip below that shows the lighting effect sequence.
