Bulb Replacement questions

Hello All,

First off, please forgive my newbness for the lack of terminology and the of the subject matter. Please view the following pictures







My driverside headlight is out (including both low/high)
I tried to pull, push and twist, twist the "bulb" out but wasn't successful...
What I wanted to try to accomplish is seeing if my passenger side bulb would work in my driverside.

1. How do I get the bulb off?
2. What do I actually replace?
3. Where do I order to replace?

Again, my apologies if i'm not asking the right questions and hopefully the pictures will help out...

Thanks in advance.

Extra:
I purchased the truck with these on.
If further pictures are needed, please don't hesitate to request
If further clarification is needed, please don't hesitate to request

 

Should be a twist lock........ Holding base and turning a collar (plastic).

Don't touch bulbs glass section for future reference..... Use nitrile gloves and or handle strictly by the base or collar.

 

those looks like cheap ass, major glare HID insert bulbs... remove both of them and the wiring associated with the bulb kit.

Buy some QUALITY 9003 factory/incandescent bulbs. I prefer the Philips Xtreme Vision bulbs.

Then take 20 minutes and read this: http://www.danielsternlighting.com/tech/bulbs/Hid/conversions/conversions.html

 

@Justus I'll pop the hood today and attempt to twist off. Thanks
