I know they are not as good as a soldered joint, but are they up to the job ?

Look like reusable Wago terminals, what do you want to use them for, temp install or permanent install, Screwfix sell them so check out their prices, you also have this option.

I`m fixing in the headlights but want the option to change them sometime, but they look suitable but these are new to me but could be a "thing of the future"

You need a connector thats moisture resistant wago's have been in use in the electrical trade for a few years now, when I swapped over my sons headlights and I just soldered the cables and used heat shrink sleeving to protect the joint, if they need to be changed you just cut the sleeving off and desolder.

You're an engineer so you should be able to work things out.

You could also use waterproof motorcycle connectors or these,

These still need wires connected to wires though, by soldered joints or otherwise. The only advantage of these is that they make an item removable.
If you use the Wagos, note that they are for a minimum size wire of 1mm squared, so aren't suitable for some of the smaller car wires.

soldered and heat shrinked is the tried and tested way and easily undone if you want to go back to pre facelift candles for originality .
