I have a Discovery 3 which has Led Headlights, can these be fitted to a Range Rover Sport? Current cars

Do you mean the whole headlight unit? If so, no. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

I'm pretty sure that the D3 never had LED lights. They could have zenon's which are technically known as high intensity discharge (HID). The later, after 2012 I think, D4's had daytime running lights which some people called angel eyes, and they were LED's.

I think the headlight I have are Angel Eyes. They are currently fitted to a Disco 3 that I bought for spares for my Disco but was wondering if they would fit my Sport. Obviously the answer is no. They do look very similar and the body lines look very similar hence the "silly question" in the title. Current cars

That's a shame, I should think they would look smart on the RRS.

They would look nice but not something I was thinking about for my RRS.

I have LED lights retrofitted to my L322 and they are/have been a nightmare. In my view if Land Rover didn't fit them don't try to retrofit them or the Canbus is going to have a headache.
