Installed mine over the weekend. Everything is a lot brighter now. (sorry, no pics)
Here's what I used:
Map and trunk lights: 31mm 1W 50-Lumen 6500K 12x3528 SMD LED Car White Light Bulb (12V) - Free Shipping - DealExtreme
License plate lights: 1W T10 White Wedge Signal Indicator Lights - Pair (DC 12V) - Free Shipping - DealExtreme
The map lights were a bit of a tight fit, but they work fine once installed.
The license plate lights could probably be replaced with something that shines downward instead of across, but they are bright enough that it really doesn't matter (they still light up the pavement quite well).
Total cost: $11.59 US, with free shipping.
