I'm having trouble with this too, but I feel like I'm getting close. I've modelled bulbs all round, and I've added a luminance (direct illumination) to the little capsules, which is meant to be the springy filament.
Its still not complete and I don't know if I will stick with this method or try another, but I hope it helps. Aventador's lights look a bit more trickier.
you nailed it, you could try adding small sphere lights for each reflector, or you could model small bulbs. i chose any kind of bulb, for me its always a guessing game and going with what i do know. my lights ain't perfect so i ain't claiming to be an expert in this . Trial and error
