Head light Help

Well I am new here and this is my first Toyota I was a JEEP man but those days are gone love my Tundra I have a 2006 crew cab 4x4. My I guess it is parking light is out it is the little light at the bottom inside of the headlight. I just need to know what light I am changing exactly so I can order a new bulb and get it changed. It is white when it flash when you look or unlock the car but amber color when the parking lights are on. Any help would be great for this Toyota newbie. Also I would like to put a front brush gaurd on any suggestions. Thanks Again Dan
