FYI, I just bought this:

After some looking around, this was a great price for GP Thunder Cree bulbs. 30W was also the brightest I came across - most were 7.5W or less. Note they are amber. I'm pretty sure white turn signal bulbs are illegal.
I did a test uninstall of the OEM bulbs. Easy. Just use a pair of pliers on the plastic tab to pull the bulb aseembly out. The tab isn't quite long enough to really get a good grip on with your fingers.
