Description

When you have a big excavating job, you have to call in the right machine for the work. For heavy-duty lifting, there is only one option, the Liebherr R 9800 Excavator.

As a recreation of the 800-tonne behemoth, the Liebherr R 9800 is LEGO's largest Technic set yet - perfect for the biggest and toughest of jobs.

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!

Light 'em up

Brought my Liebherr R 9800 to life. I've purchased many Light My Bricks kits and never encountered a bad component. Carefully following instructions and taking your time equals success.

Brilliant thanks great kit.

Looks absolutely brilliant only had one problem with it I but that was my fault I trapped a one of the wires and it broke. So a bit of soldering later and we’re all ok again. One thing I did find is that your postage is very expensive considering, other than that I’m over the moon with it easy to to follow instructions and a very good all round experience. Thanks Nick

Well packaged product with easy to follow instructions.

Having received the Lego set from a friend I wanted to see how I can improve the experience and seeing the video on YouTube sold me. With authentic looking flashing lights and detailing, the Light kit is a great addition to the Leibherr model.

Although it is not recommended to build the model and lights at the same time, this is a good thing as you want to be careful with the wires, plugs and components and having to worry about the two builds at the same time may be too much for the less experienced builder.

Although there are no build instructions in the kit, there is a well thought step-by-step guide online which shows how you should build the kit and even route the cables so that they remain tidy and safe from any model movements.

I would say Light my Bricks lighting kits are mandatory for any model and my next purchase will be the Bugatti Chiron kit. Recommended!

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.
