Puzzle. How to control each lamp individually by switches

A nice little puzzle found on internet, the components and wiring must stay as they are now, by just adding 4 components to the circuit how can you get each switch to control its individual lamp below? This shouldn't be a problem for the more experienced here but still a nice little problem.
Solution to follow later.

Solved it with 3 components

If we're not counting wire as a component, then it's possible with just one component..

One component? Have got to see that, after which I'll post the original solution

Unless something just went way over my head, if you control each lamp individually, they will no longer be in series.

The original circuit is as shown you add four components to allow each switch to control it's corresponding lamp. Although some have said they can do it with less components, very interested how they did it

A small hint, the four components are identical

I can do it with one. That's easy. But what I'm saying, is that if each lamp is controlled individually, they're no longer in series, as your description says.

So, @skylight- do all the components need to be kept in series?..

No the original parts and wiring stay as is , additional components and their connections are added to circuit

To elaborate anymore would give solution away.

If the word series is confusing the problem I can remove it
