Sawaruita 16PCS Light Up Building Bricks Multicolor LED Light Brick Sets Classic Transparent 2x2 2x3 Building Block Accessories Kit Toys Compatible with All Major Brands

These were fun additions to a child's Lego bricks set. We had to remind him to detach lights to save batteries after playing. They lasted a long time and he had a lot of fun using them in many different ways.

Lego lights. Work great. There is a black plastic stick that turns the square lights on. Don't lose it. Lol the round lights turn on by turning the top of the light. Nice that you can put the lights anywhere you want. The colors are bright and some even blink.

These *mostly* worked well, a few were tricky to turn on and needed to be taken apart and adjusted to work properly. Great value though, and my kids loved them. The lights lasted much longer than expected.

As far as these bricks are concerned, they’re really nice light bricks! All of them worked, that’s the first thing I checked. Also the vendor added a small zip bag of miscellaneous lego pieces, as a “thank you”, I thought that was really nice. What I didn’t know before I bought these was “how these bricks turn on/off. Was it hard? Easy? Tricky?” It turns out that on one-side of the brick, there is a slide switch. In this case, its a 2x3 brick, so the switch is located on one of the narrow side-ends. They’re very easy to turn on/off. I guess the tricky part will be “how to build this in” where the slide switch is easily accessible (or in some of my pre-made kits, Star Wars, Avengers, which brick to replace). These light bricks did arrive after the expected delivery date and Amazon copped to the delivery delay as it sat in a Amazon Facility for a few days before being handed off to the USPS, which then delivered it the next day. All-in-all, I’m very happy with this purchase and recommend this and the vendor.

Muy bueno

Fits nicely on other Lego bricks! Long lasting lighting! Recommend buying!

No information on operations, but work out use.

At least one piece came defective (or with bad battery). The part that removes to replace the battery is far too easy to remove. Even if an adult was using these, it would be annoying to have them come apart so easily. We purchased these for our son, and had to remove them from use due to this. Absolutely not safe for children at all. I realize they are likely designed for adults, but children love things like this too. I don’t want anyone’s child getting hold of a button battery.
