This is a master light switch Lucas (LU30731) for the TR6. The unit sells for $30 (USD) plus shipping and taxes. I am offering this switch for $30 (CDN) plus shipping or am happy to bring it to a future TTC event.
Courtesy Lamp and Plinth
Early TR6s (1969 – 72) had a plinth (635436) and courtesy lamp (BHA5138). The plinth straddled the prop shaft at the rear near the parcel shelf. The courtesy lamp has a built-in switch. The courtesy lamp can be an upgrade to the later cars. The plinth/courtesy lamp retail at TRF for $59 (USD) plus shipping and taxes. It is offered for $60 (CDN).
