Hi Ross,
The problem could have been as simple as a loose connection on the switch.=
=20
One of those red wires goes to the sidelights and the other to the panel li=
ght switch.
If both were burned only close to the switch heat generated by a bad connec=
tion at the switch may have been sufficient to burn the first couple of inc=
hes of those 2 wires.
You will need to check to see if there is damage further along either wire =
to be sure.
New instrument lighting wiring often does not come with replacement harness=
es so that would be where I would look next.

Subject: [Healeys] Headlamp switch
Gents
On a recent outing I noticed smoke emanating from under the dash when the h=
eadlamps were switched on. My 13 year old son thought we were going up in f=
lames and decided to walk home. With the lights off no more smoke or burnt =
plastic smell occurred and I easily beat my son home. I disconnected the wh=
at was left of the two red wires, no damage to any other wires. The switch =
is the original Lucas unit for a 1958 100-Six. Should I assume that it was =
the switch that failed or should I be looking for something else. The harne=
ss was replaced during the restoration but the switches were kept.
