1989 Digital Dash soldered bulbs?

Postby GTU89 » Tue Nov 12, 2019 5:45 am

What bulbs do these take? They are the small soldered type, can you buy the sockets and bulbs anymore or do I need to put strip lights in it or something? Three of the 4 bulbs are burned out. I believe the car is 6/89 build date?

try pc74 for small bulbs and pc168 for larger bulbs. I don't have a digital dash so this is a guess.

Here is a snippet of the thread where we last discussed this on the Board:

Markings on the bottom of the smaller-type bulb 'socket' says "12V 3W ALBA", so obviously 12-volt 3-watt to start with. Socket hole is ~3/8" diameter, plus the little tab-holes on either side. Interestingly, the original bulbs are soldered to the socket's contact-tabs. The plastic of the socket is really brittle from heat and age on mine, obviously. I searched a little, and found nothing comparable. You could TRY a PC37, it might fit, but it won't be bright enough. If you can solder, you could either direct-solder some 194 bulbs to the socket-rail in the cluster, OR install some LED strip-lights along the bottom instead.
From some other research, I believe they are the 74/T5 type. Ill have to purchase that and try those. They seem to be the correct 3/8in size.
Also seems to be 37/73 So you were correct before with the 73 and are still correct with the 37

Tried bulbs with sockets that were listed as: T5 73 74 3528 and they didn't work, just a tad too small and didn't reach the contacts on the digital dash (circuit board?)

10 Instrument Panel Light Bulb CML 71113A3LF(PC74 / Dorman 639-008)

These do work, the led versions from Amazon were wrong socket size despite listing 74 as compatible.
