What you need is what is called an alternate action relay.=C2=A0 This is a=
bi-stable relay that will change from OFF to ON or ON to OFF each time the=
coil is energized.=C2=A0 Like a pull chain light switch.=C2=A0 I remember =
seeing such a device with an indexing cam that maintained the relay in the =
state which ever was activated.=C2=A0 A quick look on the internet turned u=
p nothing like that but there are a couple similar-acting relays that use e=
lectronics instead.
Here are a couple that work on 12 volts:

Subject: [Shop-talk] Fog and Driving Lights
I have long wanted to install 1 fog and 1 driving light on my Alpine, and h=
ave them wired so that I can light either one or both of them.=C2=A0 There =
was a period 4-position rotary switch for doing this (off - on1 - on2 - on1=
&2) and I have one, but it is ugly as sin and I=E2=80=99d like to come up w=
ith a more attractive solution.=C2=A0 Ideally, I would like to convert an u=
nnecessary toggle switch space on the dash to a fog/driving light switch.=
=C2=A0 My hope is to put in a DPDT momentary switch (something like this on=
e, but hopefully I can find something more attractive: https://www.amazon.c=
om/Heavy-Handle-Momentary-Toggle-Switch/dp/B000LFVFA8) and a pair of latchi=
ng relays.=C2=A0 The tricky part is that I=E2=80=99d need the relays to lat=
ch on with the first pulse and turn off with the second.=C2=A0 So, up once =
to turn on the fog light, down once to turn on the driving light.=C2=A0 Up =
or down a second time to turn off either light.=C2=A0 Hopefully, that makes=
sense.
Does anyone know if such a relay exists?=C2=A0 If not, is there a simple ci=
rcuit that would make a standard relay work as described?
Thanks,
Jim
