Thanks for the CMOS and headlight relay suggestion Larry.

For now the stock bulbs for my newer E4 headlights are pretty bright
(haven't measured volts present though) but doing the work while in
there is not much more effort.

Not to get too far off base here but, can the CMOS you point to be
used to make a timed delay for an interior light?

Something like this?  http://home.cogeco.ca/~rpaisley4/LM555.html#33

Seems the Mk3 light *might* fit:

   and would be much easier.  ;)   I think Alistair Bell has posted of
this, or a similar one but thinking it might not be too hard to build
the circuit.

Neil.
