I don't understand why you have lights on either side of the windows except to illuminate the driveway/ walkway. I would select a more minimal light like you see below that comes in a variety of finishes that can be adjusted to shine light up/down or both directions.

I do not think 'decorative' light fixtures are appropriate for this location.

You could still combine this selection with a squared off decorative light at doorways.

Thank you! What do you think about color?

You might want some wall lights to blend into the siding color and some decorative lights to contrast the siding.

Paint the existing fixtures black or charcoal.

Are these decoration or functional? IE if you are trying to light the driveway a simple downlight would be best. If these are supposed to be decoration just to add sparkle to the side of the house I would ask what you don't like about what you have? I also prefer dark sky compatible when possible.

Oops I just read you have to replace them so painting them is out.

Outdoor lighting should follow Dark Sky to illuminate only the areas that need to be lit and only the degree of illumination needed.

Lights that shine upward or outward such as those shown above should never be used; you want to illuminate the path along the house, not the eaves, the wall, or the neighbors' yards.

I like this Bradford Outdoor Night Sky Wall Sconce which is available in several sizes, is not so bulbous, and would sit closer to the wall.
