External lanterns for stone gateposts?

[Wizbit]

Hi all,
Just wondering if anyone out there could give me a bright idea...a customer is looking to have lanterns installed on top of external gateposts..however, top stones are pyramid shape (bit like the photo below)
I've never seen something that would do this without creating some kind of bespoke iron-work legs..but wondering if anyone may have a bright idea or know of a light that I could suggest to them? (price no problem.. ;-) )

replace the capstones for flat ones?

I was tempted!...

Just mark out the footprint of the selected lamp and use an angle grinder to cut off the top of the diamond the lamp base will cover the cutoff perfectly. Customer approval req of course.

Lights on the front face rather than the top?

All good thoughts, thanks

Yes, customer started out insisting on having something atop, but I'll throw these options at him...

I too would have suggested on the front but the customer gets what the customer wants.
It's not a quick job.
One idea...
Subterranean link, conduit sneaked up the backs, channel cut at the top of each pier, hole drilling through centre of capping, metal conduit through the hole, choose a Victorian post top style lantern.

Core drill down the middle of the post top and then fit a tubular post light fitting to fix it use an epoxy anchor resin if you drill down far enough then the cable can enter the post lower down and be hidden
