ᐅ Attaching a Solar Light to a Stone Post – Looking for Ideas

Hello dear forum members,

I could use some advice on the best way to attach a solar light to a stone post that holds a house number at the beginning of our driveway from the street. The reason is that the number is made of stainless steel and is basically invisible from the street in the dark when attached to the stone. We do have one on the house as well, but the driveway is about 30m (100 feet) long.

The problem object looks like this:


Walkway with gray concrete post next to metal fence; large gray stain on the post.


This is how the light should/must be mounted on it.


A hand opens metal gate on concrete post; visible sign saying 'Video monitored'.


Here are some more pictures of the light itself.


An LED light panel lying on a wooden table; wine glass on the right, small parts scattered on the left.


This is the bracket, note the mounting holes.


Close-up: hand holding black plastic piece with two round indentations; table in the background.


I actually want to anchor the light with screws. However, I’m worried that the stone might chip because I only have about 1.3cm (0.5 inches) of clearance to the edge of the corner. I first tried silicone, as seen in the first photo, but it didn’t hold the light at all.

I would now be interested in your assessment or ideas:
The material is similar to paving stones or a curbstone. Should I be concerned that it will chip? If so, how should I proceed? Is there a construction adhesive suitable for this? The mounting bracket also does not offer a broad surface for attachment, only these narrow grooves. I’m unsure whether any adhesive would bond securely there. In addition, I would prefer to be able to remove it later without leaving severe residue. The silicone stains in the first picture are already annoying me.

*Drill without hammer function using a glass drill bit.
*Attach the carrier plate to the lamp with screws and firmly secure it further down.

The way you hold it against it won’t work at all, any delivery driver will just leave your package there, or you run around the corner and the lamp is gone.
A surface-mounted light fixture on the block would work.

A panel light mounted directly on the block might work.

No, no one leaves packages there. We’ve already received around 30 packages reliably at the front door. I don’t see why a light for the dark would change that. And going around the corner isn’t an option because there’s a public flowerbed next to the kindergarten parking lot.
By the way, “panel light” is a good search term. Maybe we’ll find something different that way.

Do you think a glass drill bit would work there? For house numbers, I needed about 5 minutes per hole with a rotary hammer (not a hammer drill but an actual rotary hammer) at 6mm/4cm (0.24 inch/1.6 inch). The material is really hard.

Then drill 2mm (0.08 inches) deep without hammer action, angle the drill approximately 20 degrees downward, and with hammer action drill diagonally downward. Use a professional drill bit.

Option 1: Use a diamond-tipped tile drill bit.
Option 2: Use a diamond-tipped tile drill bit again.
Move the two holes inward and drill diagonally. Additionally, use a washer for each of the two screws to make it a bit more stable.
