3.2 gauge/instruments bulb size
 

Does anyone know what size bulb goes in the gauges of the 3.2?
Thanks,
j.p.

From memory, I think the bulb number is 3898. I hope someone else chimes in...

My SC uses 7mm bayonet bulbs for the illumination light and a smaller blade style bulb for the idiot lights (Osram 2721?). I don't know when the bulbs and gauges might have changed but they look the same through 89.

I bought aftermarket led's(light emitting diodes) they are brighter. I did a search on ebay,and found a guy who sells these.
His ebay handle is 911porsche1 Go to ebay and email him, I got a set of 9 for $35.00

John, FYI you can get 9 BA7 white LEDs for $13.41 plus $5 shipping from superbrightleds.com

There are a couple of types of bulbs used, for gauge illumination and for idiot lights. From the Porsche spec book:

2W BA7s
1.2W W2x4.6d

Translating further, from PET, Porsche part numbers:

N 017 751 2
N 017 751 2

And, superceding to items carried by Pelican:

900.631.103.90 4W #3893
900.631.132.90 1.2W #2721

And, a link to the light bulb page on Pelican, for those who need it:

Hope this helps,
