Brightening the Headlights

[Bob Culver]

For purposes of tracing junction to junction voltgae drops it matters little if it is from 6v or 6.5 reference as measuring the drop and not the total. Much more constant with the motor off and no confusion from spark hash which Sevens generate like the Titanic radio transmitter. On many cars the dip switch was just to handle the momentary high but mostly low current of the solenoid reflector and is not suited constant filament load of rearranged systems. On the cars with focussable bulbs the beams can be "bright" but very sharp for modern roads with distant edges and marked lanes.
