BRIKSMAXBRIKSMAX Led Lighting Kit for Iron Man Helmet - Compatible with Lego 76165 Building Blocks Model- Not Include The Lego Set

Lights work well but you may need to find some extra bricks to secure and snake the wires properly. The instructions have you putting wires between bricks and that really doesn’t work well. I found using the a couple round one piece bricks made it easy to slip the wires through and still provide stability of the model. There are usually leftovers in other sets so I had a few on hand.

This worked for less than 24 hours and was extremely hard to assemble. The pieces are super duper tiny. The connections are cheap. What a waste of money.

Legos are always dependable
