Make a sticky-out triangle/ V-shape from mirror glass and attach above lights.

Take the bulbs out of the up lights.

I have put two up and down lights on my fence beside patio and they are all wired in now. I feel the light shining up the way is wasted and was wondering is there any reflectors I could screw on above each light to make a feature but also keep the upward facing light from being wasted. I thought about something similar to a metal hood above your cooker but obviously a lot smaller. Were would I get something made for this purpose or has anyone any ideas?
