This upgrade is awesome. Adds much needed light to this Lego set. Take your time when installing. Read instructions thoroughlyI thought using a lighting kit with Lego flowers was such a cool idea so I decided to try this brand of lighting kit.I gave only four stars because when I was looking at the instructions, I thought I was missing pieces and sent back for a replacement. I received the exact same pieces in my replacement. Turns out the instructions do not exactly match the labels and colors of what you receive. I was looking all over for the light labeled red. The wire was red, not the light. Also was looking for a separate package for the adhesive foam squares. They were in a bag with something else and did not have the label on the bag per the instructions.Once that was figured out, was pretty easy to install.
