Do I need to replace my original 1953 headlight switch now that I have converted to a 12 volt system? I have seen headlight switch advertised for my 53 as 6 volt or 12 volt. What is the difference?


The truth will set all men free.

They have differences in the amperage rating. You should be able to get one at a good NAPA parts store.


There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

I believe (and I'm sure I'll be corrected if I'm wrong!) the 6V systems use higher amperage. 6V systems use heavier guage wire, too.

So the 6V part should work for either!

If your 6 volt lamps were about 40 watts, then the 12 volt bulbs at 40 watts draw 1/2 the current of the 6 volt.Your swich if in good shape is fine.

Boyo and Tony are right. The higher the voltage, the less current, meaning your 6 volt switch will last far longer than a 12 volt. smile

J. H., I don't?? :confused:

I've been running my 54 with 12 volt for 3 years now, no problems. I think it's just a sales gimmick, they are probably the same switch, diff labels. Why would they have two if one would work for both? :rolleyes:

Jim, me and Joy keep hearing talking also. Happenened at night when all is quiet.Yesterday she found one of those talking picture frames was the source.We still hear talking in our heads even after removing the battery from the talking frame.

Maybe the difference between the 6 and 12 volt is in the rheostat for dimming the gauge lights.

This morning at 4:55 am EST, as I was sitting on the top of a dark hill with a few friends in my 1954 pickup, I started to worry about my original 6v light switch (with rheostat) burning out earlier because of the 12v conversion I did in 1972. Not to worry, if it gives out before I do, I had the foresight to buy a few used switches for replacements (yes, they also have rheostats).

The light show early this morning was exceptional (brings back memories of early 70's light shows that flashback every so often).

Did I hear a vacuum leak or was that just voices from the past? Maybe both. I don't mind the talking in my head but I would like to know where to buy those picture frames.

I had hoped to take more people stargazing this morning but my '54 suburban is still not put back together.

Your original 6 volt switch will work fine on 12 volts because the 12 volts will require approx half the amount of current to accomplish the same thing Shhhhhh do not tell your original switch and it will never know.... grin grin grin
