I made this Night Runner circuit for my car and scooter.
At night it gives a very good effect and can also be used in the daytime.
I have a switch to switch it on whenever I want to.
In the Knight Runner circuit, the 555 is wired as an oscillator.
It can be adjusted to give the desired speed for the display through a 500k variable resistor.
The output of the 555 is directly connected to the input of an IC. CD 4017
Each output can deliver about 20mA but a LED should not be
connected to the output without a current-limiting resistor 330R in the circuit above.
Using six 5mm LED’s, the display can be placed in the front of a car to give a very artistic effect.

I have reserved this step for a video which I have not yet been able to load to my Instructable.
