ok here is a list of what i bought for my 95 lt1 a4. the 6le overlay is clear so i need color leds to maintain factory color. if using the stock gauges, white LED's will show up blue do to the blue film on the stock overlay. you will also have red/orange redlines and you don't necessarily have to change the idiot lights.
7 blue 194's for gauge and needle illumination.
3 blue 194's for high beams and turn signal indicators (**** green).
6 red 194's for check gauges, brake, seat belt, low coolant, air bag, and i switched to red for the low oil instead of orange.
4 amber 194's for security, SES, low trac, and ABS INOP. add 1 if you need skip shift and add 1 more if you need low trac.
2 white 194's for glove box and center console. i would recommend wide angled with 6 led's for maximum illumination.
5 blue 74's for door panel pinholes, shifter plate (a4 only), and HVAC.
3 white 4410's or 212-2's for the rear view mirror and dome light. the original dome light actually hooks around the contacts but i simply bent them inward and it works fine. the mirror will be a direct fit. the lenses pry towards the windshield and fall out. i recommend a pick like a dentist would use.
the headlight switch needs an LED soldered in with an appropriate resistor.
superbrightleds.com is where i purchased everything. what is difficult with the gauge bulbs is the old filament leads extend down the socket, solder at the bottom, and come back up the sides. i was using a pocket knife to break the solder and pull the lead down from the side. the bulbs won't pull out of the socket, they break. superbrightleds does carry led's already in the sockets, but i didn't see any that would work.
