<VV> More light down da road

[JVHRoberts@aol.com]

In theory, a great idea, but in practice, there's a significant problem. 
You'll lose the low beam bulbs VERY quickly, for two reasons:
1. It's a LOT more heat than the innards of the bulb are designed for, and 
you'll overheat the envelope and possibly explode the bulb all over the insides 
of those nice headlights!
2. The 'common' connection from the bulb to the base WILL overheat and burn 
through in a short period of time, like less than an hour. 

You may ask how I know this. I ruined a Cibie H4 headlamp this way, and lost 
a replacement bulb from frying the common connection.

Calling all headlamp experts!!

A while back I installed a nice set of Hella E Code headlamps in my '66
Convertible.  They are really great.  However, the thought occurred to me
that when using the high beams, the low beam filament in the outer lamps is
switched off and the high beam filament is turned.  Going on the theory that
more light is better light, why not leave the low filament burning and turn
on the high beam filament during high beam operation.  I don't need to worry
about excessive load etc. as I've already installed relays and heavier
wiring.  Is there any problem running both the high and low beam filaments
at the same time?  I did a short term test in my garage and nothing blew up
etc.
