Hey Porken,

Thanks for the list. I have been wanting to do this to my OB. I am just waiting to do the fuse panel and ground cleanup. I appreciate you sharing your research with the rest of us

j.kenzie@sbcglobal.net

Just my opinion but I think someone should quickly answer any of Ken's questions to he can get back to work inventing 928 stuff. .....Porkensioner.....

Frank,

Thanks! It took all day! Mainly, I'm prepping the car so 'Honey Bunny' can drive it. But really, I just like to have all new bulbs on a new car!

I'm sure a vendor (Specialists?) could put together a complete kit for 1/3 of the retail per bulb price for all these. I did all the bulbs from blister packs on the '81 when I bought it - that was expensive.

PorKen

Note - many of the bulbs come in boxes of 10! (Updated in the chart with *s)

I guess I'll have to do both the '86 and the '81 too!

BC

I have been watching one vendor in particular with reference to the LED lights. It all looks so snazzy.

PorKen

It's Christmas!



Actually, this is about half of the bulbs - I couldn't wait, and replaced a bunch at my friend's shop!

Here's the 85- gauge warning lights. These are larger than the PRND32 bulbs.

The early type. The oil pressure is similar but reversed.

Great guide, thanks Ken!

Anyone have a cross reference list for the same locations, but with LED bulbs?

RFJ

Thank you Ken.

The thing with LED alternatives is that there are many choices that one must make concerning colors, brightness levels, price, and what modifications one is willing to do. Also there is the lost functionality of the bulb check computer, cruise control, and an ever present 'stop lamp' warning.

These should work for all cars up to but NOT including S4 models. All bulbs were purchased from superbrightleds.com

And for MY '83 instrument pod, your needs may vary:
Warning lights are B8.5D socket, RED X14, Blue X1, Green X3: B8 LED Bulb - SMD Instrument Panel LED
Pod illumination X3: 194 LED Bulb - 5 SMD LED Tower - Miniature Wedge Retrofit
Pod switches, GREEN X2, WHITE X1, RED X1, AMBER X1: 74 LED Bulb - 3 SMD LED - Miniature Wedge Retrofit
Resistors for foglight, trip reset, defrost, and emergency flasher pod switches, 1.2k ohm should work? 1/4 Watt Carbon Film Resistors - Through Hole
Clock, HVAC, cigarette lighter bulbs: BA7s LED Bulb - 1 LED - BA7s Retrofit
Not sure if I will go through the trouble of replacing the hard wired bulbs for high temp, low coolant, low voltage, and low fuel but these may work: T-1 style LED bulbs
I will make a standalone thread once I have finished and am satisfied with the results. Hope this helps.
