So I'll try and keep this short, go on Amazon and get yourself a spool of LED from Amazon like these (make sure you get waterproof to be safe)

Then just replace the 110v plug with a 12 volt plug, something like this (or wire them up to the 12v in some way that better suits your application)

And there you go. The LEDs are adhesive backed, so you can stick it to the canopy frame, or just get some Velcro or reusable tie wraps like these-

It's the cheapest way to do it, with a little creativity, you can get as fancy as you want with the install, and with the remote, you can set the color and brightness.
