JD 730 electric start light switch for JD 70 conversion

I have a John Deere 70 diesel that was converted to electric start. I bought it that way and may eventually convert it back to a pony start. In the meantime it needs a new light switch. The John Deere 730 electric start tractors which my 70 diesel conversion was modeled after have two different light switches - one is for a tractor with 2 lights and the other is for a tractor with 4 lights. The 2 light tractors must have the lights coming off at the rear hood and the 4 light tractors must have fender lights. The JD 730 two light switch are around $140 and the switch for the 4 lights are around $70. I know the difference must be the resisters on the 2 light switches. Can I buy the cheaper switch and make it work since since this tractor will probably be converted back to 6 volt pony start sometime in the future? I will gladly put a $60 switch on it, but the $140 switch seems steep for something I might not use long. Thanks.

Was your 70 conversion done using the 24 volt system of the 730? Heavy duty 12 volt starters became available quite some time after the 24 volt 730s came out and conversions from 24 to 12 volts were done. If yours is a 12 volt system now, it MAY make a difference which light switch you need.
 
(quoted from post at 17:59:52 05/14/20) Guys it is the 730 24 volt system that has been added.

If this doesn't need to be "original" and you want to keep the cost LOW, just use one or two DPST toggle switches, could use one for each group of lights.
