Review: D11 Lego tech nic light set - This is an awesome kit! Perfectly designed to go with the D11 technic set
Review: Great Kit, Terrible Instructions - First, the good: The materials are great and they go together well to complete this model. The lights are easy to assemble and add realism to the already great Lego D11. The parts come in clearly labeled packets that are referenced throughout the build. Now the not so good: the instructions suck. They are not the worst instructions I've ever seen, but they are far even being considered "decent". Going on line, it appears that different versions of this kit were made and the few online videos I found used the earlier kit version so there's no help there either. I hoped Briksmax would have a better version on line, but their online PDF is for the earlier kit version, so again, no help. What's wrong with the instructions? They just aren't clear. In many cases, you can't tell were the wiring goes or see how you are supposed to run it or even mount some items like the terminal boards. And since parts of the bulldozer are black, the black wiring disappears on the pictures. For the instructions, simply using white or lightly colored wires to make them stand out would help a lot. Also, there is nothing in the instructions about mounting the battery box, so you're on your own. Fortunately I had some extra Lego pieces and was able to construct a mounting surface on the rear of the D11. If the instructions were clearer and more complete, this kit would rate 5 stars. As it stands, I can only rate it 3 stars and would have given it 2.5 had it been possible.

## Questions & Answers

**Q: Can it be installed after the machine has been put together**
A: Absolutely. I was very skeptical initially but it was fairly simple. The instructions left a little to be desired. They did not always make it clear where the wiring should terminate. However, the effect is rewarding.

**Q: Will it contain the bulldozer lego bricks?**
A: No. Must buy separate.

**Q: Are there instructions to install when you build the bulldozer?**
A: Yes, there are instructions with pictures showing each step of the installation.
