Drafty recessed lights

I have recessed lights in a vaulted ceiling that get drafty when the temperatures go down. How can I fix this?

The problem is probably that the recessed lighting is cut through the vapour barrier and not surrounded with it. This means that the recessed lighting box only has a thin layer of insulation protecting it from the cold air in the attic.

It might not be easy to fix depending on the insulation type and size of your attic but the best way is probably to find the light box in the attic and close it in with vapour barrier,
Either form a cover with plastic vapour barrier sheets and tape or you can purchase preformed vapour barrier for going over top of recessed lighting. Make sure you tape all the edges down around the existing vapour barrier and recover with insulation.
Hope this helps.

I must caution you about can lights. There are two types:

1. Cans for NO insulation.
2. Cans for insulation.
What kind of Cans do you have?

Putting plastic Vapor Retarder and insulation over a non-insulated can could prove to be mistake.
