Recessed Lights Make Popping Noise

Moved into a new house about 2 months ago, and the recessed or can lights in the kitchen area make a popping noise. Have done several web searches, but haven't been able to find an answer has to how to fix this problem.
Just wondering is anyone might know what's causing the popping noise and how to fix it.
Thanks

Some types of recessed trims, like "Halo" brand use two coil springs to keep the trim against the ceiling and like Tony said, when the plastic ring heats up, the expansion against a cool ceiling makes a tick or pop sound. In the past, you could contact Halo, and they would send no charge, replacement metal trims rings, which won't expand.
