While mounting lights on the house my better half pointed out the lamps are angled because of the siding. What I'm wondering do they make a panel that mounts behind the lamp base that will make the light vertical?
Thanks for your time.

Arlington Industries, and probably several more make products that allow fixtures to mount flat on siding.

I included a picture from their website: http://www.aifittings.com/k_6.htm

These can be found at home centers in the siding section.
