Very nice but don’t unravel lights at once!
Good quality materials with very bright lights (which looks amazing in the dark). The printed instructions are pretty worthless but the video tutorial is excellent. Will definitely consider lighting kits for some other sets. One warning: this may be obvious to people with common sense (which I sometimes lack) but do not unravel all the lights at once or you will end up with a horrible, tangled mess. Even thought lights are all one string, each “section” is individually wrapped so you can unravel as you go. Again, probably very obvious but I initially missed that.

Good kit that lights up set nicely
Great kit that lights up the set really well. Wires are a bit tricky to place at times but it’s expected for such small wires.

A dream castle
This is one of the "best" buys we have done this year. My 9 years old took the challenge to finish the Harry Potter castle (18 years plus lego set) during summer vacation. Once he did that I gave him this light set to make this wonderful looking castle look like a dream. I was amazed to see he did that with little or no help. The lego set looks so good now.

Buying for other sets
Obsessed with this light set. Used it for my Hogwarts castle and grounds LEGO set and it's so beautiful and vibrant. It was a little difficult reading the directions but it turned out amazing. It came with the piece as described and it doesn't come with batteries.

Worth the money
This light at is awesome! It only gets 4 stars because of wire length. The instructions are very clear, and it looks amazing!

Great Quality
These lights are so cool. I ordered them along with the lego set for my boyfriend and he had a lot of fun putting it together. We've had them for about a year now and the lights still work perfectly fine! He said it made the set more fun to put together as an adult because it added an extra step to the process. The instructions were easy to follow along with as well. He added the lights as he was building the set but they also give you instructions on how to add them after the set is already built as well!

Requires careful reading of the instructions
It looks great! The below-ground displays can now be seen. It does take some careful disassembly of the model. The directions are pretty good, although the wires in the photos are difficult to spot. It wasn’t clear that you start with the LEDs closest to the battery. I started with the wrong end and had to undo. On the whole, the kit was better than expected.

Lovely little light kit
My son saved up his pocket money for this and was not disappointed. Quite fiddly to build took about half an hour but the resulting light show on the castle was gorgeous. We’ve had this a while now and the battery is still going strong. Really lovely little kit.

Dramatic change with the light kit
I was aware when I purchased the Tailighting kit that It didn't include the Lego build, but they did send me a message after purchase to confirm I knew that the Lego kit was not included. LOL. The installation instructions in the included assembly book is/are vague. But, online videos will walk you through the install process. It's delicate work feeding the wires, but the end result is worth it. The Castle looks incredible with the lights.
