Flashing \!/ Dash Light

Yesterday I decided to finally deal with the dark dash lighting in my 88 Turbo. I replaced all the indicator lighting and the three gauge lights with LEDs, checking each bulb and polarization and cleaning/wrapping the reflectors in foil. Everything went fairly smooth however when I got it all back together and started the car, the master indicator now flashes every second or so. It flashes briefly and goes back out at a constant cadence.

I suspect the polarity map I used for the dash has a few bulbs wrong as the parking brake indicator lights are not lighting up (although the big \!/ lamp lights appropriately when the p-brake is on). I thought I would ask this group prior to pulling the cluster back out again to address specific bulbs so I don't need to do any more repeated disassembly/assembly than I need to if it is not bulb-related.

So, any thoughts or guidance on a flashing \!/ dash light?

Yep, go back to incandescent bulbs for the indicator lights.

The \!/ light is an annunciator light, designed to turn on when one of the indicator lights is turned on. Using a diode instead of a resistor type bulb will cause all kinds of weird indications.

Grumble. Thanks George! I suspected that might be the solution. Is there a better replacement bulb for the indicators or is it back to the stock parts? What is the best part number/aftermarket bulb to use for the indicators?

The stock parts are designed to, umm, err, work as designed...

There's a kit that puts reflectors in with LEDs. It has the beneficial side effect of turning the ! light off (to me that light is total overkill). I found it on 944only I think or eBay.

I chose to get a strip of led's in the UV range and epoxy them to the periphery of the gauge cluster inside, bottom. There's a channel there that they fit perfectly. The big change is that UV led's are like black light and boy did it make the gauges beautiful. Holy Cow!

Some people try to turn back their "odometers." Not me. I want people to know 'why' I look this way. I've traveled a long way and some of the roads weren't paved.
