<div>I have been through 4 headlight switches in the last 2.25 years. The quality is just so poor. 12 uses out of first one, 8 uses out of 2nd one and the last one lasted 3 uses and gave out in the dark at the start of a 1,283 mile trip over 6 days. I had to sit on the side of the road and wait for the sun to come up. A buddy had a two position 50 year old Sunbeam light switch we installed hanging under the dash on the first day of the trip, whew.</div><div><br></div><div>1973 MGB, original owner with 234K miles and the original switch lasted 230k miles. Take your original switch apart and do everything you can to retain it.</div><div><br></div><div>Never any smoke, the switch just gives up the ghost. Supper poor quality, mechanically.</div><div><br></div><div>Installed Halogen lamps from a buddy with Moss relays and 4th Moss switch. I have only used 3 times, so we will see if this works.</div><div><br></div><div>Good luck.</div><div><br></div><div><br></div><div><br></div>

<p>In that case it sounds like it was an output from the light
switch that shorted. Either the blue (headlights) or red/green
(parking and instrument lights) is probably also damaged, which
will indicate (pun not intended) where to look next.</p>
<p>Note that if the short caused enough damage inside the switch to
open the circuit, and disconnect the short, manually reconnecting
the wires will likely bring it back on again. With your cut-off
switch on tap first one then the other of the wires mentioned
above onto the brown and you should soon see which has the short -
if it's still present.<br>
