Best "stock" looking solutions I found were Hella H-4 Assemblies. 7-inch round with flat face is available from Susquhana Motorsports. A variety of H-4 bulbs in Halogen and better techologies is available there. HellaH-4's with rounded fronts are available from Rover's North (on the web).
I put the flat face on my PCA stock 914/4 2.0 for night races with 65/100 bulbs. I believe these will work with the later technology bulbs that they offer in H-4 bulb formats.
If you want LED conversion bulbs, and proper flasers to go with same, go to:

I have a lot of instrumentation, and I used red LED's for illumination, blue for blue indicators, red for fuel reserve, and green for green indicators.
DO NOT USE AN LED FOR THE GEN (alternator) INDICATOR. THE RESISTANCE OF AN INCANDECANT BULB IS REQUIRED FOR PROPER SEED CURRENT FEED TO THE ALTERNATUM.
