Should work, I think. Just connect the first one to one light and the =
input of the second, then the other light to the output of the second =
relay.
What you are doing is effectively binary counting, stepping with each =
successive press of the switch:
00
01
10
11
00
=E2=80=A6
Although I would question why you would want fog & spot lights on =
together =E2=80=93 I wpuld have thought one or the other =E2=80=93 =
it=E2=80=99s either foggy and you want the wide flat short beam or clear =
and you want the narrow longer throw.

If I recall correctly, a pair of old VW headlight dimming relays would =
be a period-correct solution. Grounding the relay by pulling on the =
turn signal lever would flip-flop the relay between high beam and low =
beam. Or, in your case, on or off. The old relays had to have the =
headlights on to power them, you would need to figure out how to remind =
yourself to turn the lights off or use a relay on the ignition wire to =
control the power.
Or, use one of them high-falutin' electronic gadgets...
