Police light flashing mechanism ( NO NXT! ) LDD
Ultimate Lego presents: The police light flashing mechanism! An easy mechanism to make police car flash lights really flash! And that without an NXT!
About this creation
You want to make a police car with working flash lights, but no NXT? This is what you need! As an extra to the remote controls it is not designed to be fit in the car, but it can be modified later to fit in a larger scale car. Now some pictures:

The car part: The receiver receives the pattern and is the connection to the lights in the car The bulbs are the grey spheres on the end of the "cable" ( here are the bulbs covered with the police colors.


Here you can see the two speed rotational gearbox that gears the mechanism. (two speeds, slow and fast. Another plus, the rotational gearbox avoids that the mechanism rotates in the wrong direction, which can cause damage to lego parts.)


The actual mechanism: The black parts are pushing the sticks foward, which causes a flash of the lights at one side. The mechanism goes like: Right, Right, Left, Left, Right, Right and so on.


For all questions and comments, just comment!

And, if you use it in your car, plz credit me!
