These solar post cap lights from HUYIENO are a super easy way to add some charm and visibility to your deck, fence, or garden.

They run 100% on solar power, so no wiring or electrician needed—just pop them on top of your posts and let the sun do the rest.

You get two lighting modes to choose from: a warm white glow for a cozy vibe, or a 7-color RGB cycling mode that slowly shifts through different hues for a fun, festive look.

Just make sure all your caps are set to the same mode so they match.

They automatically turn on at dusk and off at dawn, so you don't have to think about them.

These caps come with three different bases, so they fit 4x4 wooden posts, 4x4 vinyl posts, and even 5x5 wooden posts.

That makes them super versatile whether you're working on a new build or upgrading old ones.

Each one puts out about 10 lumens, which is plenty for ambient accent lighting, and the built-in 400mAh battery keeps them shining for hours after sunset.

Built tough for the outdoors, they have an IP44 waterproof rating and are made from UV-resistant ABS plastic.

Rain, snow, or blistering heat—they hold up fine.

The diamond-shaped shade adds a nice decorative touch too.
