Interior LED Changeover (uhm...Looooong)
#47

Am I correct in remembering that you can no longer dim the LED's?? That to me seems to be a disadvantage. Are the LED's bright enough to bother your night vision?? I typically like to keep my pod lights pretty dim, but that could just be me.

If anything, it would be nice to at least be able to turn the LED dash lights on and off... Maybe with an additional high intensity wash switch in place of the dial? How much are the dimmer units that were talked about?

I have been gearing up to do an LED conversion. I didn't realize that there are wedge shaped LEDs available - silly me. What I am trying to accomplish is replace most of the dash/console incandescents with tri-color LEDs so at the push of a button I can change the color of the light. Simple setup would yield 7 different colors - red, green, blue, cyan, magenta, yellow, and white. I popped off one of the pod switches and placed the lens over one of these LEDs - looks really nice. I am afraid of not having enough space in which to wire the LEDs though, as there are 4 leads per LED. Also, I'm not sure how to handle the power supply; I bought some 5v fixed output voltage regulators @ radioshack which accept up to ~30v, so between 12.6v at battery and 14.4v with engine running, the LEDs should remain the same brightness. I want to use the existing wiring and install a voltage regulator just after the fuse/wherever the lights get common power source from (headlight switch?). Only issue is that I would have to swap all the lights at once because I couldn't have LEDs and incandescents both work on a 5v circuit.
Is this too complicated? Should I go for single color LEDs instead?

in my swap i just did the instrument cluster backlights...all others (radio/hvac/pod switches) are still in the traditional ambers.....my dim still works, but not smoothly, for instance, when i scroll the dim, the lights fliicker until it is at just the right setting....but it works. i have them set as low as possible, because at night they are very bright...when the headlights are off tho, and cluster is in daytime running mode, its perfect and they are much clearer for daytime driving...they look like a modern audi cluster now
i also changed the obd lcd to all red, it looks much more modern

You missed it. I don't remember exactly where I posted as it was in the midst of several post, but the car was in this thread https://rennlist.com/forums/928-foru...ts-coming.html
The pics are now gone as the hosting site pulled the plug, but here are pics of the car and dash. There is not much difference in the changeover for any year car except for the lighting of the instrument cluster....that info can be found all over Rennlist.

I really love the lighted HVAC fan ****.
I replaced all backlights on the ***** in my 86.5 (with traditional bulb), and was really disappointed to see porsche didn't bother the fan ****, despite is has the same look as the pod controls.
In case I upgrade to LED, I am certainly also doing the fan ****!

BTW, I have that steering wheel and used to have it in my 944. I painted the "Vulcan" grips black. I think it looks much better without the contrast. Car still looks awesome.

Keith, are these the LED's you used? If so which ones specifically?
i.e. which of the below did you use for each applicaiton?

finally!, I know you didn't ask me, but I've got an early draft of what will ultimately be a rather comprehensive guide to upgrading interior lighting to use LEDs. The section entitled "Parts Summary" near the end with recommended bulbs is complete, so feel free to make use of it.

Major thanks to Keith—and a couple of other people I mention in the document—for the trailblazing work they did in this area.
