Dave,
Please note that at 236K miles, the cluster lighting on our 92 started to fade, not go out, just fade. Upon disassembly, it was obvious that the white reflective plastic had deformed and discolored from the heat of the halogen bulbs. The clear prism was also deformed.
The solution I used was two 1 watt white LEDs and a current source to drive them. Mods were needed to the prism (hole drilling) to accommodate the 1W LEDs. The following link to a picture is on the old style prototype cluster, note that the passenger side is a bit dim since I broke the prism on that side. Here is the link: http://www.flickr.com/photos/8498733@N02/5685090809/in/photostream
The same mod worked perfectly on the 92 cluster, I normally run it at 50% brightness at night which is twice as bright as the original halogen bulbs. If you want details let me know, I'm willing to share the thermally "cool" solution to the lighting problem.
Higher power halogen bulbs will just melt the cluster.
