Here I have for sale a new old stock Lucas 54121 boot lamp

The lamp is operated by mercury which flows and when your boot is

opened, it completes the circuit and the lamp comes on, when you close

the boot the circuit is broken and the lamp goes out .... Quite ingenious !

Was originally fitted to the Rover P4 & P5 as well as various

Jaguar models including the XJ6, XJS & MK 10

and probably many other vehicles of the 1960s & 70s

I have tested the lamp and it operates as it should

These are no longer available and very rare now.
