914World.com _ 914World Garage _ PN for instrument bulbs

Posted by: Chaznaster Oct 7 2021, 08:42 PM

Hi. First off apologies for a question that has probably been answered before. I just could not find the reference in these pages or elsewhere.

I am looking to replace the instrument illumination bulbs - probably with LEDs - and was able to ID the incandescent ones: 90063110290.

For the life of me I cannot find the PN for the tiny bulbs that go in the plastic holders and indicate high beams, turn signals, etc. I only have one that works. I am also looking for a replacement plastic holder as one of my is missing.

Any information would be much appreciated.

Thank you.

Here's a link for LED bulbs:

It's advisable NOT to replace the alternator light with an LED.

As for the socket part number, it would be helpful if you had a PET diagram:

There are 4 different sockets for instrument bulbs, 2 larger & 2 smaller, Both have single & dual wire spades. Shown with std & LED bulbs (btw these LED's work with dimmer function)

here they're shown;

Thank you trick-e, 9146C and barefoot Thanks to you I am almost there. The parts guide is really a useful thing.

For reference, I have two size bulbs in my dashboard (6 of each)
* PN 90063110290 or BA7S | 2W: on the bottom in pic below
* PN 90063113290 or 2721 | 1.2W | W2x4.6d base: on top in pic below

The 1.2W 2721 is so dim, I cannot even see my highlights indicator when it is on. Interestingly, for the 2721 there are two similar incandescent bulbs: 2022 (2W) and 2023 (2.2W) that might be worth a try if the LEDs do not work.

Looked for the superbrightleds for the BA7S but they are out of stock. There are a ton on Amazon so will try a dimmable one
Also found options for the 2721 to try.

I’ll send a link if they work.after I get them and test them.
