Original Light Bulb Numbers

Recommended Posts

I have some Packard light bulb questions that hopefully someone can answer as I'm looking into making 6VDC LED replacements. I know that a Studebaker collector already did this some years ago but he is no longer doing so and I can find no one else making them either but I would also like to update my database with the proper information.

 

The originals were probably Mazda and I have the owner's manual information for some of these years but it is missing some needed information including quantity.  On most it's obvious but on others it is not so I hope someone can help.

  • What is the original back-up light bulb number and candlepower for 1948-1954 Packard?
     
  • What were the original bulb numbers and candlepower for the headlights? (The owner's manual gives only the wattage)
     
  • How many instrument lamps were there? (Excluding the status bulbs such as oil pressure, generator, turn signal indicators, high beam, etc.)

 

Thank you!

No info on the backup lamps for 48-50.  Those used those chrome things that are almost like small fog lites and there were also a lot of aftermarket assys installed.  53-4 used 1133's at 32cp.  I believe 51-2 would probably use the same bulb but don't have definite info on those.

 

Speculation only on original info for headlights.  Packard used their own part numbers but on my 47 the bulbs are 4030s.  I believe those were what might have been used from 23rd thru 54.  Dons bulbs doesn't give cp but does give the specs on those bulbs as 45/35 watts which is slightly more than the wattage in the 47 and 48 manual.  It is the same wattage as listed for 23rd thru 54.

 

The dash illumination lights should be 4 on 51-4 clusters and 8 on 48-50s.  Don't know how the LEDs would work (or fit) with the UV filters used on the 22-23 series but then I also don't know how many of those clusters still have enough of the luminescent paint on the "Flite-Glo" instruments to work with the UV.  There are a few though and some on the packardinfo forum have bought the modern equivalent of luminescent paint to redo their instruments.

Thanks a bundle! I had forgotten about the luminescent dash of the '48-'50 so that might make it a challenge and I no longer own a Packard in that era for reference.

In the meantime, looking through my owner manuals, I seem to be missing the one for 1950 and it is not on packardinfo.com but I have the '49 23rd series manual. Would the bulb specifications be the same? There so seem to be subtle differences between the '48 and '49 22nd series charts so I wasn't sure about the 23rd series.

From what I see with a quick glance of bulbs in the parts manual the 22 and 23 series use the same bulbs so that makes me think all the 23rd whether a 49 or 50 are virtually the same electrically.  Interesting is the headlights are listed the same for 22-23 in spite of the different wattage between the 22 manual and 23 manual.  Don't know if it was a misprint or if they upgraded the bulbs after early production or just consolidated stock for all after the brighter bulbs were introduced.

I see that those I've listed so far have the headlight wattage of 30-40 while the 23rd series and up list it as 35-45 watts. However, there is no mention of the candlepower which is what I really need.

 

I see also that the 22nd and 23rd series use 1158 bulbs for the taillights and 1154 for the turn signal/parking light. I wonder what an 1158 is and how it differs from an 1154. Was the 1158 the one without the staggered guide posts? Otherwise the canglepower is the same and both are dual element.

 

My '48 manual is the 3rd edition; my '49 22nd series is the 6th edition and my '49 23rd series is the 2nd edition. I don't have any idea of how many editions of each there were  of each and I presume that there was a '50 manual too but, as I mentioned, I don't have it. I would love to hear from others with these manuals with higher edition numbers in order to try to glean which was the last made.
