The current draw of the old lamps was 3x .06a (180 ma total)
the draw of the 3 LEDS is 60 ma 3x20 ma.
The entire circuit in question is mounted on terminal strips behind where the bulbs go in.
I'm pretty sure all I need to to is add a resistor to gnd at the far side of r160, to keep the voltage about 3-4 volts, the LEDS are pretty forgiving about what you give them, and even if I damage a few while working out the correct value, I have 100 of them to experiment with, and they are small enough to solder into the shells of the old bulbs after the glass has been removed.
