Neighbor has an 8N Ford which was converted to 12 volts prior to his purchase. The lights are not hooked up and there is no switch for them. As a goodwill gesture I told him I"d get the lights working. The lights are sealed beam Westinghouse A43. I"ve done some searching on the internet for these sealed beams but came up with nothing. Anyone know if these are 6 volt or 12 volt lights, or how to tell the difference between 6 and 12 other than hook them up and if they get real bright and burn out quickly then they were 6 volt. Any other way to tell?

TIA

I agree with Dave. Hook the lights up in series. If they are suspiciously dim, then you can assume they are 12V bulbs and parallel them.

No reason to replace a good bulb just because you don't know what it is!

To go along with Dell's info.. he is indeed correct.. ge 4419 is a 12v bulb.. and ge 4019 is the 6v version.

if in doubt about your bulbs.. pull both of them.. wire them is series and hook across a 12v battery.. if they are dim.. they are 12v bulbs.. if they are bright.. then they are 6v bulbs..

Bob..... ..as you know, lightbulbs come in "standard" sizes that makes them "interchangeable". You just gottta find the right size with the right voltage specification. I have a note that the GE-4419 is the 2-terminal 12v equivalent for the standard 8N Tract-O-Lite sealbeam headlite buckett.

According to Haakem's Razor, yer Westinghouse A43 is most likely 6-volts and thats probably the reason that they weren't wired up to the missing push-pull light switch.

Me? I'd just take the headlite rim in to a regular autoparts store and BUY 2-new 12-volt bulbs that fit rather than "guessin" what the volts rating of the current dimm-bulbs are. And at the same time, buy a fuzed push-pull replacement liteswitch. Simple, eh? And wish yer neighbor "merry christmas"; no charge'em.

Ain't original, but so what, neather is 12-volts. BTW, 12v litebulbs have about TWICE the candlepower of 6-volt bulb; good reason to change..... ....respectfully, Dell

Hook them in series. If they look okay, they are 6volt. Leave them like that if you wish. I have done this on four or five tractors already. If a filment burns out you lose both lights, then you go to the parts store nd decide what to do. Simpul! AND CHEAP

I just put some 12 volt bulbs on a case tractor I have and they may fit the Ns also. the number of the bulbs are 410 and 411. Both are 12 volt but are made just a little differant as far as the way they look. I know they look like they would fit in the head light brackets I have on one of my Ns.

I purchased some 6v bulbes at TSC, if there is one near you go look on thier shelf the no. should be the same. or call you NewHolland dealer.

I think the original 6V bulbs were about 35 Watts meaning they drew about 6 amps. So, it you tied one of Dell's secret ballast resistors (just 1 of the 2) in series with the 12V battery and one of the bulbs you'd get about 6V at the bulb. One of Dell's secret resistors would cut the voltage about in half if it is a 6V lamp. If they are 12V lamps you'd see that they were to dim.

I would suspect, as you do, that the bulbs are 6v. But to be sure, you could take the bulbs out of the light housing, and they should have 2 screws on to back that the wires attach to. Hook up both bulbs in series with each other and put 12 volts to the series combination. Are both bulbs bright? If so, they are 6v bulbs. If they are both dim, they are 12v bulbs.

To do the series wiring label the bulbs #1 & #2.
Fasten a piece of electrical wire between one screw terminal of #1 and one of the screw terminals for #2. Take a 2nd wire and fasten to the open screw on #1 and attach the other end to a 12v batt terminal. Take a 3rd piece of wire and fasten it to the open screw of #2 and connect the other end of this wire to the other batt terminal. Both lights will light, or neither will light. If neither, then one is burned out. BTW lights do not care what is + or -. The wiring system on the tractor is called parallel wiring. If you have a good multimeter, you can do an ohm test to determine whether the bulb is 6v or 12v. But you will also need to use ohm's law (E=IxR)...Heck, I'd just wire up the series experiment and find the answer that way.

Bob: Failing identification, I'd put 6 volts on em and see what they do -- if they're real dim, chances are they're 12 volt, if normal, 6 volt.

This is by far the easiest method, but it requires the use of a 6v battery, and I assumed that since the tractor was converted to 12v, that a 6v batt was not available. Ahhh, if you have a combination 6v-12v battery charger, then just set it at the 6v setting and hook up a single bulb to the charger. If it is bright, well then it is a 6v bulb. If it is dim, then switch the charger to its 12v setting and see if the bulb is bright. New 12v bulbs of this size are available from NAPA for about $10 each and fit right into the standard 8n headlight housing.

Well, I see what you mean about the internet search. I tried Google, entering many different words & combinations and NADA !
Just a thought: could you use a multi-test meter to check the voltage? I am not familiar with their use, but I know people here are always using them to check other electrical components on the tractors.

Thanks, Bill. Certainly worth trying.

Carl, I think you"ve got the right concept but its not the voltage. Its probably going to be a measurement of the filament in some electrical term. Thanks.

Thanks to all of you for your recommendations and advice. I"ll run a quick check on the bulbs with a 6V charger and then likely head for NAPA.

This is indeed a gift for the neighbor.

Happy Holidays

Bob
