Bringing old brass glass sconces into the twenty-first century is easy with this two-step paint job. Simply disassemble the light fixture and coat the individual components in a shade of spray paint that contrasts with your house siding. If you can't remove and paint some of the components, don't fret. Re-assemble and mount the sconce to the siding, taping off the glass and sticking brown paper to the siding to protect it from paint. Then, spray paint the exposed trim, let dry, and flip on the light to see the results of your good work.
