So, instead I bought a can of black semi-gloss spray-paint for $3.50 and got to work. I could just buy a light later and save some bucks.
I removed the mailbox and house numbers and painted them with two coats of paint. Once I put them back up, I wasn't satisfied because the light still looked like junk-ola. I'm not interested in messing around with electricity (although I have installed a ceiling fan before - Bravo).
I removed the lower portion and unscrewed the fixture and placed a plastic bag around it. Painted that with a couple of coats as well - being very careful to NOT spray my siding!!
Once back together, I thought it looked nice and fresh! You can definitely see the address numbers now! What do you think?!
