The side marker bulb you are asking about is a built-in amber bulb (looks like an LED to me), not as easy to replace, but doesn't mean you can't do it. It's right below the amber side reflecter in the headlights.
The parking light is the one that usually gets replaced, upgraded to an LED bulb (stock is incandescent).
I used the bulbs in your link
2 V-LEDS WHITE 194 13 LED LIGHT BULBS 158 168 2825 to replace the parking lights. They are whiter and brighter than stock. I think they look great. Bummer they are out of stock. I used the same bulb in the rear cargo area.
