Can we do this? (aka The DIY Cruise Control Thread)

With a DPDT switch you'd still need a circuit to toggle the LED on and off. The circuit becomes simpler (a flip flop using two transistors or one IC), but is still required, as the switch is a momentary input, rather than a toggled one.

I get it now.

If someone can come up with a tidy module to make this work, it could be a minor cottage industry. It should work with the OEM switch installations, as well as the improvised ones.
