Reply to "Wiring Multiple LEDs with SPST Switches"

Leo,
Most of that makes sense. So then I could use either a 10mA or 20mA for a warm white LED? The difference would be the brightness, is that correct? If so, is it the difference in the mA value or the wattage (1/4W vs 1/8W) that changes the brightness?

Chuck,
Your reply has me confused. Could you please clarify?

Mark,
That is an option, thank you. I really like the turn signal idea.

Chief Bob,
Thanks. I've actually bought quite a few ready-to-use LEDs from Evans Designs (and love them). Ultimately though, I'd really like to understand how to build my own. The reason being one - price and two - I like being able to understand how things work.

To further confuse myself, what is the math/equation to determine how many LEDs I can operate on one 12VDC power supply?
