Headlamp

2002 Mazda Protege 5. I noticed the right headlight was burnt out. So, I looked in the manual and it had instructions on how to change out the bulb. I had done this on my old car (Jeep Cherokee) so I figured 'no problem'. I bought the bulb and in the process of swapping it out I had some trouble. There isn't much room to work with because of the arrangement of other parts... I accidentally snapped off the piece of plastic that holds the metal clip that holds the bulb/wire in place.

Do I have to take the car in and have the whole headlamp part swapped out or is there some sort of heat resistant glue I can use to hold the light in place? The light works, but it's not secure, and I don't want it to come loose and burn something else.

Any help would be much appreciated.
