Recently added 1960s-1970s new old stock flat-faced French Marchal Ampilex halogen headlights to my '67 1800s. The low "city beam" bulb is in the reflector in the rear of the lamp, the high beam is a combination of the low beam light and a bulb in front of the small reflector.
When on high beam w/all 4 lamps lit there are 440 watts of light produced or 3100 lumens.
Based on these figures, I am wondering if any of you electrical whizz's can help me figure out what amperage headlight relay (or relays) are needed when all four bulbs are lit?
Planning on adding a separate circuit for the lamps - what gauge wire should be used for these lamps and what size fuse?
How many amps does the alternator need to produce without being strained to power a combination of all the lamps in the car and the high beam, windshield wipers, the ignition, and the original Volvo dealer installed Frig-A-King air conditioner blower motor has a 20 amp fuse.
What capacity battery does the system need for this power load?
