Austin 7’s have a Lucas\/CAV 6v generator that on a good day, going flat out will outup about 8 amps, so that’s 8 X 6 = 48 watts minus about 5 watts for the ignition so that leaves 43 watts, not much of a budget when one headlamp could use 32 watts . So no night trials? Some people will fit an alternator but the easiest way to hold back the darkness is using LEDs. <\/p>\n\n\n\n

LEDs have a long life if they do not get too hot, most of the cheapies on Ebay fail after a sometimes surprisingly short time they are not engineered thermally or electrically but some good stuff is coming through but they will cost cost you a few more shekels. <\/p>\n\n\n\n

The Austin like many cars and motorcycles of the era have BA15d based lamps these are like stop tail lamps without the offset pins.<\/p>\n\n\n\n

I am trying some LEDs from BMH Trading<\/a> in QLD that are sold for motorcycles and are negative earth (yes Austin’s were negative earth until they changed their mind) There are some available for A Model Fords from Logo Lites<\/a> in the US that I think have the same base that come in positive and negative earth and like these work 6v or 12v that could be worth a try.<\/p>\n\n\n\n

As the Chummy was pretty happy just to have lights without all this fancy dipping stuff I have wired them for low beam on the sidelight position and high beam on main so I don’t have to add another switch and these on low beam only draw 3 watts each so they can be used as parkers anyway.<\/p>\n\n\n\n
