- I have these three strobe lights and I want to make them flash
- synchronously, with minimum interconnection. Here is the schematic -
- I may have interpreted wrongly so feel free to tell me if something doesn't
- make sense:

- C | | L Light

- I've tried to connect them directly - at the terminals of the
- light bulb, because that is the most accessible and simplest connection,
- and it works for two bulbs, but I fear trying a third will overload the
- single transistor that would probably source all the current in a case
- like this.
-
- First of all - am I right that ONE transistor will source all the
- current? And second, if I am, what other way is there to interconnect these
- oscilators so that they are in phase but power themselves seperately?
-
- I hope the schematic is clear enough - if you have any questions
- about it email me and I'll update it...
