Spyder Halo Projector Bulb Replacement

[SeriousBlack]

I installed a pair of "genuine" Spyder halos on my Canadian '07 hatch this summer. No issues with fogging/leaking/condensation or electrical, but this week the DRL/Low Beam bulb burned out on my driver's side

Both halos and all other lights (including the cheesy LEDs that I never liked) all still work. The DRL/low beam bulb is the one closest to the side reflector.

Has anyone replaced one of these bulbs? If so, could you please let me know the following:

1. Bulb Type/Model No.
2. Best place to get them
3. a quick DIY in terms of removing the old one from the housing etc to minimize issues like condensation etc

Thanks!
