how do i remove them & put in new ones ?

 

Two Headlight Retaining Clips on top of the assembly and two screws on the bottom in the gap between the bumper.

 

Thanks ...how do u get clips off. ?

 

There is a tool that looks like a "T" (see diagram on clip). If you do not have something like that:

Take two small hex key/allen wrenches, insert the short ends in the top of the clip (see diagram on clip) so that it becomes a "T".

I used a vice grip to hold them together and pull up, be prepared to sacrifice the future use of the aforementioned hex key/allen wrench. The larger the hex key the stronger the tensile strength.

Using a screwdriver to pry will bend the clip(s) and you will have to get new ones.
