dash panel lighting issues
I didnt get pix, however once i dissassembled everything, i removed the blue light diffusers, repainted the inside of the housing with fresh gloss white spray paint, cleaned everything up, and ran a true 12V into the panel. I must be used to the newer cars i guess where the lighting is more even. But it doesnt look bad now. Everything is pretty visible.
I also cleaned all the printed circuit boards in alumiprep 33 to remove the tarnish, rinsed thoroughly, and using the ole weller soldering gun, i soldered all the pins to the boards.
I may add 2 more LEDs inside the housing to even out the lighting, but thats about it.
The ones i am using are a direct replacement for the GE 194 bayonet type, and fit into the stock bulb holders.
One place you cannot use an LED in the dash is the brake indicator in the dash. You have to keep a light bulb there. Reason being is it gets power from either end. One end from the park brake switch, and power from the low brake pressure warning switch on the proportioning valve. LEDs are directional meaning they light only one direction. Reversing polarity they wont light.
So using an LED there you may get your parking brake indication, but not low brake pressure.
