Hi! I recently added the lightkit from Brikxmax to my Ninjago City (70620) and I wanted to share the result.
It was extremely fiddly (having big hands does not help in the slightest) and took around a whole day with a lot of cursing and cussing. Parts fell off in all directions. The hardest part was holding the top two levels in one hand whilst trying to attach the light cables into the expansion port (everything could have come tumbling down but fortunately it didn't).
The result however became something I am really proud of. I find myself just looking at it for periods of time and imagining out stories for each of the mini figures.
I also have the Ninjago City docks and the corresponding light kit but I have not had the time to put it in yet. Hopefully soon!
Hope you like it!
