First, let me say, UBER_AR, you have a great site here. It's an awesome resource for allroaders.
I just completed allroad_RS27's DIY fix for the overhead dome light, as mine was intermittently working. It looks like I had the exact same issue that they posted the fix for. After reading through their instructions, I was able to complete the fix in about 15 minutes.
I also noticed that my luggage compartment dome light was having the same issues. So, I pulled it out and sure enough; the solder had a hairline crack around a pin which was basically in the same exact place as the center dome light that allroad_RS27 discussed in his posting. However, for the luggage compartment light, there are only two metal bridge blades and only two corresponding places they slip into the circuitboard. The pin closest to the silver (not gold) metal blade was my issue.
