This was my third Briksmax 2.0 set, and this was impressive. The Home Alone set alone is an expert build, and the lighting kit takes patience, but I promise you that it will be worth it. It looks incredible when it's all put together, and I have received so many compliments. The specific lights included in the kit help highlight the many details of the lego set, which makes me appreciate this even more.
While it is recommended to add it after the LEGO set has been built, I decided to try to install it while building the set for the first time (the kit came first before the LEGO set). For me, it was a little easier to maneuver the wires and set up more as I built it. However, it required me to install it out of order. If you like reading the instructions and putting them together in order, then I wouldn't go this route. If you do decide to install the kit as you build, take the time to plan out how you will do it. Either way, it will look amazing!
