How do you test a headlight switch for a 1989 200TQ Sedan?

The obvious response is "the headlight is burned out."
But if they both went at the same time, then it could
well be the switch.  Or remotely when one bulb burned
out, the "extra" juice killed the second one.

One thing to be aware of, if someone has relayed the
headlights on the car using a single relay for the low
(or high) beams, a dead relay would kill both lights.
That's one reason to go with individual relays for
each light (2 low, 2 high).

In an emergency, you could jump a wire or two from the
remote start post or alternator directly to the (low
beam) lights, bypassing the switch.  The lights would
be on all the time, but you wouldn't be grounded.
