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.

Step 1: Step-1

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

Nice work, but what the use??
Knight Runner? I think you mean Knight Rider.
YES- I deliberately changed the name to sound different.<br /> Night Runner runs in the dark?<br />
First thing i thought of was cylon&nbsp;
Hi.<br /> This is a great instructable!<br /> I would love to build a couple of these.<br /> Can you please make the diagram a little larger or maybe add a parts list?<br />
<strong>Part List for Night Runner.</strong><br /> <br /> <strong>Capacitor</strong> <br /> 1uf<br /> <strong>Resistors</strong><br /> 22k=1, <br /> 500k variable type=1, <br /> 330 ohms=1.<br /> <strong>Zenner Diodes</strong> 1N4148=10<br /> <strong>Red LED's</strong> 5mm=6<br /> <strong>IC</strong> 555 and CD4017=1each.<br />
Nifty little circuit, I can see some ways to use this one!&nbsp; Keep the circuit small and it will fit under the back of my bike seat, a great attention getter tail light for night rides.&nbsp; A buddy here wants one made with slightly brighter LEDs for the end of his boat dock.&nbsp; On a dark lake, the ripple of light will make finding his dock a cinch!&nbsp; I'll build that one in April, and run it from a battery pack and recharge with a small solar cell array.<br /> <br /> Fine project and a great Instructable!!!<br /> <br /> <br />
