6 to 12 volt lights

I have a ford jubilee and switched it to a 12 volt system with a gm altenator that is self regulating. Now i want to make it 12volt with my old generator and a 12 volt regulator. My problem is the lights. I want to keep the same 6 volt lights because 12 volts are exspensive. is there a way to do this and reduce the voltage to 6 for the lights?
 
I doubt it. I had the same issue with my Oliver 77 when I went to a 12 volt generator. Those use a special bulb that isn't available in a 12 volt that fits the socket. I put a ballast resistor in it. That didn't work. It smoked the bulbs anyway.
Unless your Ford sockets can be changed to a 12 volt bulb. I think the last parking light bulb that I bought for my 85 Ford pickup cost me a whopping 30 cents.
 
Are they a sealed bulb if so Steiner Tractor Parts has just the bulb in 12 or 6 volt for around $15.00.
 
Thanks for the reply. I'll check that out. Can i use the same generator and just replace the regulator with a 12 volt one?
 
tcgman: Do these lights have a sealed beam bulb? I'm not at all familiar with these, but if they are, or are any of a variety of automotive bulbs, it's much simpler to swap the bulbs out unless they are something incredibly odd or special.


rrlund: Did those Oliver bulbs have the 3-pin neck? I may have some of those, but don't know offhand what combinations I'd have of 6 or 12 volt, and SC/DC bases. If you have a 6V number I think I might have a chart somewhere to find a 12V alternative.

these lights are seal beam. I just looked on steiner website and they do have them for aprox.$15.00. thank a bunch for your help.
 
I have never converted one to 12 volt. When the 6 volt generator on my tractor went bad I replaced it with a 6 volt alternator. I have kept my tractors on 6 volt and if maintained right I have found no need of a 12 volt system.
 
Ya,they have a flat flange and I think 3 pins. I've been told Deere used them in a 12 volt,but when I checked,the parts guy looked at me like I had two heads.
 
D, I agree completely. Simplest, most practical and definitely the least costly.

I know a lot of people run 6 volt starters on 12 volts, and get away with it, no offense to anyone... But it just can't be good in the long haul.
 
Hard to say. It doesn't really say what the length and diameter of the base are. Look similar though.
 
I have a tractor that I converted that still has the 6 volt lights. I wired the two front ones in a series. They work just fine. When one burns out they will both go, but then I will just buy two 12 volt lights. The rear light is a 12 volt.

It has been this way for a couple of years.
 
rrlund: The ones Bob referenced may work. They are single contact, 25 watt, and only rated for 100 hours. For under a buck, I would give them a try. The one reviewer even said he used them on a tractor.

I have 1044, 2326, 2336, 1026, and 1074 bulbs with the 3-hole flange and double-contacts.

I have a few 1507, and I think I may have some 1327 bulbs somewhere unless I used them (one or the other may have fit a microfiche machine I had, IIRC) with the 3-hole flange and they are single-contact.

The above are all rated for 12 or 12-16 volts. I have alot of 6 volt stuff as well.
