Thats great! So about 5 seconds eh? I'd think that for a festoon the
cap(s) would have to be much bigger. But maybe 3 of those small LED's
would be plenty?

FWIW, my thought was to install the push button on the cowling above
the steering column. Hate to drill holes but.....

Maybe use an adhesive backed switch like this?

I originally thought to use this with a larger LED festoon somewhere
mid dash pointing down (maybe something along the lines of a map
light. One that is also switch on the 30 buss) but it wouldn't be hard
to ground switch that gizmo in the door light switch circuit and just
use the OEM dome light. The other thought is that like my Honda
Accord, wire a small soft light LED near the ignition tumbler. When
drivers door is closed, that light comes on. You can see which key to
select and find the hole.
