update for you!!
i managed to remove the light covers with my swiss pocket knife
always go from the right side as the end of the bulbs are inserted in at the left.
so use the knife and picked on the top right corner of the plastic cover, bend it out a bit and work toward the left and you should be able to remove the light housing.
there is a 2ndary protective cover in there, so you have to remove the clip from right side gently first then pull the left side out with a bit more force.
in order to get the bulb out of its socket, use the knife and push the bulb from its end between the connectors and you should be able to get the bulb out, the put in the new LED you wish to install, remember to check if the bulb lights up before you install it all back together!
good luck!
