I got the Neo-3 regular 2 lumen from and in hindsight I think the 6 Lumen HP's would be too much. And to answer someone's question from earlier in the thread you are looking for the T1 not the T1.5

They fit in a bit tighter than the original bulbs. This proved a bit difficult when taking them out. I ended up having to use two jewelers screwdrivers to pry them out when I needed to turn them 180 degrees to get the polarity right. It also bears noting that you will probably want a few different size flat head screwdrivers to find the right width to install them. Not sure why they made that Philips head looking thing which approximates the flat part of my #3 Phillips head bit but the bit would not grab so I used a flat had bit that had the right width to fit and grab.
When it came to the dimmer switch I had to Modify the bulb a bit. First I made sure I had polarity right. I could see a dim bit of light in the dark at full bright so I knew it was on. As this bulb goes in the side of the switch I marked the base of the bulb with a sharpie toward the front where I would want the LED to shine. Using an x-acto blade I cut the plastic sheath down to just above the lock tabs. This exposed the resistor and solder joints which I proceeded to gently bend 90 degrees in the direction of my mark. Then reinstalled it a viola this one is just as bright as the others.
Lastly the info switch bulb. I had to take the switch apart to get at the bulb. While I was in there I used a pencil eraser to clean up the switch tracks and contacts that would occasionally read DISC on the read out. So then the fun; the bulb was sandwiched between plastic backing and the PC board. If I were doing it right it looked like the only way I could switch the bulb would be to de-solder all the pin connectors to lift the pc board off the plastic base. While my soldering skills are ok I figured it best to take a different rout and not risk melting the plastic backing. Out came the high speed rotary grinder and I carefully cut a circle the size of the wedge base out of the plastic allowing me to remove the old bulb and install the new LED. I can't be entirely sure but It seems to me that I left plenty of plastic there to maintain sufficient structural integrity to the plastic back.
If someone else has worked on the info switch and found a better way I would love to hear about it. As far as I could tell the connector pins would not come off the plastic bit without removal from the PC board. I suspect the dealer would just replace the switch if the bulb blew. Honestly, thinking about it, I cant come up with a good reason they put this bulb in the switch the way it is; while the others are easily changed once the switch is out of the dash.
Summing it all up these bulbs worked out well. Although they are not as tall as the factory incandescent bulbs they have a sufficient beam that lights up the switches right nice. A minor mod and the squat bulb that was in the dimmer switch works well. They dim and brighten just as if they were incandescent bulbs and are available in a variety of colors. They are significantly cheaper than the dealership bulbs and will last significantly longer if not for the life of the car.
