Just a quick tip/reminder for everyone…
If you are dealing with a metal roof, awning, (firetruck!) or any metal surface, we highly recommend you look into magnetic clips. This is by far the quickest, easiest way to put lights on a metal surface. Simply attach the clip to the light and drop them where you want them, thats it! They hold very well and will stay in place all season.
You can find them for both C7 and C9 lights. They can be hard to find in stores, so your best bet is to look for them online.
Have a great day!
