Resurrecting another old thread to post a bit of advice... I just finished installing a nearly identical (in both shape and cost) 12 LED dome light array in my VX. Hard to say whether it's technically brighter than the standard bulb, but the light is clear and crisp and you don't have to worry about the power draw and heat that you do from standard incandescent bulbs.

Now to the advice... although you can buy these kits on eBay and elsewhere with 4, 6, 9, 12, or 15 LEDs, the MAXIMUM size that will fit in our dome light housing is the 12 LED wafer. It's possible that there might be identically sized wafers out there with a higher number of smaller LEDs, but in general 12 is probably the limit.
