Re: Would the US electrical code allow this ?

As already stated, you don't switch neutral, and you don't use the ground as a current carrying conductor.
If you had another conductor from switch box to light, you could change switch out for a 3 way, one position = light the other position = led. But I guess you already knew that :grin:

Re: transformer question - how to calculate?

Turns ratio = Np/Ns
Where Np = number of turns in primary and Ns = number of turns in secondary.

Voltage ratio Vp/Vs = Np/Ns

wher Vp is voltage on the primary and Vs is voltage on the secondary.

Re: Bad Bulbs?

Another alternative, if you have access to do it, wire all three bulbs in series. That'll give you the dim light, and lower the voltage to the bulbs.

Re: CAN'T CLICK LINKS

Have you tried to right click , then go down to print?
I can't picture what that yellow splatter you mentioned looks like. Since it's with all 3 browsers, have you checked mouse settings, for "pointer"
