This four-pack of swaying solar firefly lights uses 24 green LEDs to create a spooky eye effect, designed for outdoor placement where the solar charging unit needs direct sun exposure rather than a wall outlet.

Check the photo for the individual bulb base size on each eyeball unit to ensure the replacement socket matches your existing fixture if you are swapping out a single failed unit from a previous set.

The MOSSNDAR unit projects 96 HD patterns and includes a remote control for adjusting the display, which is critical for positioning the beam under a low eave without climbing a ladder.

Look at the product image to verify the physical diameter of the projector lens housing, as a wider base can clip against the roofline if the mounting surface is narrow.

This 2026 upgraded model features clearer ghost HD patterns and is marketed for home windows, suggesting a compact form factor that should fit within standard window sills or small eave overhangs.

Examine the photo for the depth of the projector body behind the lens; a deep housing may protrude too far under the eave, causing the moving ghost images to clip on the roof edge.

This dual-season unit offers 10 slides and 80 patterns, including ocean wave and firefly effects, and is rated for indoor and outdoor use, which implies a sealed casing to protect the internal electronics.

In the listing photo, identify the specific outlet type required for power, as this model does not list solar charging, and you must ensure the plug fits your available outdoor GFCI outlet without needing an adapter that adds bulk.

Featuring ultra-bright dynamic RGBW water ripple effects and 15 lighting modes, this projector uses a remote and timer to manage the display, which is useful for scheduling when the light is mounted out of reach.

Check the photo for the filter model or lens cover design, as the RGBW color mixing requires a specific optical path that might be obstructed if the unit is tilted too sharply under a low roofline.

This waterproof LED projector is designed for holiday decorations and parties, with a general-purpose form factor that should accommodate standard mounting brackets or flat surfaces.

Look closely at the product image to see if the unit includes a dedicated mounting bracket or if it relies on a flat base, as a flat base may slide on a sloped eave and cause the projection angle to shift and clip.

This model projects 10 colors of aurora and ocean wave effects and includes a remote and timer, allowing you to adjust the brightness and pattern without accessing the unit directly.

Verify the bulb base type in the photo if the unit is modular, or check the overall width of the housing, as a wide body may not fit under a narrow eave and will cause the light beam to hit the roof structure.

The 2025 upgrade version offers 30 HD wave ocean effects in a 2-in-1 moving landscape design, intended for outdoor waterproof use, which suggests a robust casing to handle weather.

Inspect the photo for the specific filter model or lens aperture size, as a larger aperture may require a wider mounting area that could be constrained by the low eave, leading to image clipping.

This 12-in-1 projector offers 3D dynamic decorations for outdoor use, combining multiple effects into a single unit to reduce the number of devices you need to mount under the eave.

Check the product image for the outlet type and cable length, as a short cable may not reach a power source if the projector is tucked deep under the roofline, forcing you to use an extension cord that adds clutter.
