Hi
I know I have mentioned this before, but some LED Stop+Tail bubs are actually just a single LED with two different values of feed resistor. This gives high/low current (and therefore brightness) depending on which one is connected to a live supply.
This generally works OK, but with some setups there is the risk of current going the "wrong" way back out of the unfed resistor, which then enters another lighting circuit.
The cure is to use small series diodes, but it's a pity they aren't built in as standard.
