The Light My Bricks light kit adds 24 individual lights to bring the Liebherr to life. Features include rotating bit light, emergency light effects and spot lights to create a realistic industrial grade machine!

Leibherr R9800 Excavator Kit

This kit was quite easy to install and set up. Other company’s kits I have used only have lights that are either on or off. This kit has the standard lioghts, alternately blinking lights and a rotating beacon. Instructions and pictures are clear and easy to follow, A plus with the pictures, they can be enlarged so the detail can be easily seen. The replacement pieces with the hole in them for the wiring to pass through was a nice touch. Light my Bricks kits are my preferred kit.

Great kit!

This kit has exceeded my expectations. The packaging is exceptional (both the box and the packages for individual components), the online assembly instruction is easy to follow, and the result looks every bit as good (if not better) as the promotional video, and every component and wire ends up hidden behind the excavator's plates. The installation can be a bit fiddly as pieces are very delicate, so it's important to pay attention during the process. The only possible negative (if I can even call it that) is that due to a battery pack, the excavator's back side becomes a bit heavier and ever so slightly leans backwards if the boom is pulled all the way up, but it's hardly noticeable, and the structure is very robust and can easily handle that.

Overall, an exceptional product!
