We'll see what happens. Hopefully, I can give them a "glowing" report. Good discussion, guys.
It's all very strange. I put a set of Pilot bulbs in my old Corvette and they do seem to work OK in it. I'm tempted to remove one and see if it also bleeds power from one circuit (contact) to the other.

The internal circuitry of these things is a bit unknown - someone said they work like a diode. I noticed in my testing with a battery charger and VOM that they will only flow current in one direction so that may well be. I also know that with the trailer relay in the ERA we are not getting a full 12 volts on the flasher circuit at the bulbs. That may or not be an issue because when a flasher relay is functioning I doubt we are getting a full 12 volts either. It may be that they need a higher voltage than my car is delivering through the flasher and trailer relayto function properly. I'm not enough of a circuits guy to fully understand the problem.

Hope they work for you - I regret my recommendations for the Pilot bulbs now as now I don't think the quality is there.
