From the early 1980s up to the late 1990s, Morgan fitted the steering column switches used on Triumph Dolomites, the Lucas part number is SQB119.

These switches originally worked with sealed beam headlights and are prone to burning out the contacts if used with halogen headlamp bulbs. This is because MMC didn't originally fit relays so the contacts have to carry the full current of the headlamps. It is highly recommended that relays are fitted if the switches are replaced.

When the switches are fitted to Morgans, the stem of the switch may need to be formed into a S bend to enable the stem to clear the dash. This must be done very carefully to avoid kinking. Some owners have reported a good experience using a small pipe bending tool.
