You can browse through Houzz and look at light fixtures ideas, or, Google for lights and lamps and there are millions of choices :) For example, LightingDirect.com

just keep them simple as the house is simple. Place them halfway between the corners and the door surround, about where they are so they will feel balanced in place.
This is a tract home. There is really not authentic name for this style of house.

Your house has its roots in Spanish ranch to best define it. The Spanish ranch descends from Spanish colonial architecture that originated in the California missions. The forward facing gable roofs give it the most definition but you also have the round tile attic vent alluding to those seen in Spanish ranch styles in California. I presume this is a California house because I see healthy sago palms in the landscape. Also the stucco makes it go that direction also. The arched impressions above the window and garage also pay homage to that architecture though their shape and detail is a loose interpretation. The clay tile roof is yet another spanish ranch element. I have attached a picture of a transitional style fixture that would look nice with this house. To give the elevation more solidity paint the garage door and the stucco spaces inside the arches the same color as the roof. That will help ground the scheme. Hope that helps.

I like the above as well as this one for your home. It echoes the arches over windows.

Thank you for your response. Love the light too! You are correct, the home is in California.
