Given that lumen output of an incandescent lamp goes with the 3.5 power of voltage, I can't stress enough about how important relays are, as well as having a sufficient supply of current to keep the headlights at their proper voltage. These nomographs show this rather clearly!

In fact, several years ago, CATZ made a voltage booster, that added up to 2 volts to the lighting supply! Not sure they still make it, but it should make for some darn impressive high beams!

i have voltmeters in the spyder dash of most of my cars. when i put the
head lights on i had an unacceptable volt drop until i added a better feed
for main B plus to the front of the cars. if i put the high beams on it was
real bad. the switch seems to handle it ok , but plans are for a relay
feed to bulbs soon. i dont use high beams often , or even drive at night that
much now so...i run extra radio stuff and a gas heater also.
the alternator is a high output later unit , working very well for
many years now.
regards , tim colson
