You would have to put in two lights and two sets of wiring. What you do is

buy one of those big (+-5/8")square full wave rectifiers (They have a

hole to mount with and heavy lugs) from Radio Shack and hook the + terminals

to each coil and the other terminal to your transition light. The other

lug should be grounded. The grounding will keep your relay and switch

points from arcing.

[I was thinking about just using a couple diodes, one from each relay,

to the single light, but your idea of using the full wave rectifier sounds

even better, what with providing the benefit of flyback protection to

the pressure switch contacts, all in a single package.

Great idea.  Jeez, I love this list <g>.

In reality this is the wrong hookup to get this job done.  To make it work

you must jumper from the switched side of one coil to one of the AC

terminals on the bridge, jumper the other coil switched side to the other

AC terminal on the bridge.  One side of the transit light goes to ground,

the other side of the transit light goes to the + terminal on the bridge.

The - terminal on the bridge also goes to ground.  Now it'll work.

computer.  It's still me <g>.
