They didn't want to pop out easily, and I didn't want to inflict any damage to the new car...so I'd appreciate any comments or directions since the lights I bought did not include any!

They will pop out.. since your car is new it may take a little more effort.. you wont break anything.. if you do it will only be the old marker so its ok

Don't just yank them out--I did that on my first Carrera, and on one side it damaged the area that the side marker clip snaps into, and the new side marker didn't sit flush as a result.

The instructions are in the bulb changing section of the owners manual. There's a plug inside the wheel well that you remove to insert a screw driver and compress the clip as you remove.

it is really easy to pop out..just take it from the wheel side ..i almost forget how i did mine..let me know if u done it..
remember becaurefull when u put the new one back..
