Just had a word with the boss, she works in a school science lab. She suggested that you should try Maplin; RS or Rapdi Electronics. Hope this helps

How many LED's will you require? Its going to be hard to find a light chaser  that operates more than 8 or 10 LEDs. Although it may be possible to wire up sets of LED's to operate from the controller, but this would depend on the LED's not exceeding the power output from the chaser circuit.

You could try the model railroad area of the hobby shop.
A local company here, Modelec produces a "traffic barricade" circuit that
will chase, or randomize the blinking of several LED...

Also somewhat local to the Pacific Northwest, USA is N-gineering...

I didn't see exactly what you are looking for, but it might be there somewhere.


You could also build your own. Google "LED chaser circuit"...

You will find lots of stuff like this...

You would probably have to make your own or modify something else, mainly to sort the voltages.

I bought something like a magic wand with LEDs in is and this is 3v. I will strip the wand of LED and controller, and then step down the voltage from my main battery with a resistor.

All you really need is a controller and a slack handful of LEDs and resistors. If you decide on the colour of your LEDs (in your case white are 3v) and the number you want, and details of your controller (Voltage limits, Amps, etc.) I am sure someone here would put a plan of a circuit diagram up for you, including correct resistors to use where.
