How do I protect extension cord connections from rain?
Seal each exposed connection using a waterproof connector gasket and termination plug to keep water out.
Do I need to cover outdoor Christmas light plugs?
Yes. Covering open or connected plugs helps prevent moisture intrusion and nuisance trips during wet weather.
Can Christmas light plugs get wet?
They can, but exposed connections are failure points. Follow our step-by-step weatherproof guide and use the right protection products.

A must for outdoor holiday lights!

I installed these on all my Holiday lights in my front yard, and 2 days later, it poured rain for another 2 days straight! So far, so good...with the Lights still on! Great customer service as well. Highly recommended!

Our outdoor lights kept getting tripped because of the rain even though they were plugged into an outdoor outlet. We added these and we haven't had an issue since. So simple and effective. Highly recommend.

Worked great. Used these to keep Christmas lights and extension cords connections dry. Haven't had a problem yet here in Maine.

I have plug-in type landscape lights with extension cords covered by mulch. I was having problems with the GFI kicking the breaker when it rained a lot. I put these on wherever there was a plug connection and it has rained a lot since - no breaker kick-off!
