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.

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.

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.

Easy to turn off and on. My 7 year oldIs obsessed and plays with his legos every day now!

A few improvements that would be made:The bricks are not a standard square shape - they are 1 + 1/3 height. Can’t see a compelling reason why. After 1 week, a couple of the pieces won’t stay lit. They also shipped with some unnecessary knock-off connector pieces that I just tossed because they don’t fit Legos well. A much better freebie would have been the cross-shaped key required to turn the lights on & off (we were able to find ours, but I wouldn’t take that for granted)In general, they bring my kids joy and are a happy addition to our Lego-creating.

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.

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

These Sawaruita Light Building Bricks work great with Lego and similar brand building bricks. My 4 year old grandson can easily turn them on and off and enjoys adding them to anything he builds but especially emergency vehicles! We also discovered that they can be added to other toys (not just building bricks) and used as lights for toy houses, animal cages and even plastic toys like Easter eggs for a fun "glow in the dark" effect! We will get lots of use from these unique and fun bricks!
