Recessed light clicks on and off

Hi-

Few years ago, I installed four recessed lighting on it's own 20 amp circuit with a dimmer.

Few days ago, one of the light wasn't lit, so I thought it blew out and was about to change, then I heard a "click" and the light came on. It would do this couple of times day so now I am wondering if this is a fire hazard?

Any ideas on troubleshooting it?

The canister is a sealed unit (square one) with IC approved.

Thanks in advance for your help!

Failing thermal protector or over wattage bulb. If you can post manufacturer and M# the pros can tell you if the thermal protector can be replaced.

I suspect over lamped for the trim installed. On the inside of the there should be a list of trims with the max size lamp approved for that trim.

Hey Guys-

It's Halo 4" 50-Watt Incandescent Recessed Light Housing, sold at Lowes

(hxxp://www.lowes.com/lowes/lkn?action=productDetail&productId=60607-337-H99ICT&lpage=none)

I have Sylvania PAR 20 (50w, 120v) bulbs installed in all four canisters.

Could it be that this particular canister is defective? I've never had issues with them before...

Yes, it could be that, as Ray pointed out, the thermal overload is failing.
Another thought, is there insulation next to the can and if so are they IC rated?

Thanks so much for comments from all of you.

Although the canister is rated 50w, I thought the bulb was too hot so I am going to notch it down to 25w or so to see if it makes a difference. I will post back with results...
