Disclaimer: the side of the car I could get pics from easily is the side that kissed the side of a mtn so my bumpers are messed up.
All you need is a small flathead screwdriver.
For the front, you will stick the screwdriver in the location shown below. You can put a cloth on the bumper where the screwdriver will be touching so you have less change of messing up the paint.
Then pop the light out
Then all you have to do it twist the bulb holder out of the lens
For the rear you will stick the screwdriver in the location shown below and do the same things as the front marker
