1965 impala trunk lamp

I have a 65 impala just replaced the light bulb and cleaned the lamp housing due to corrosion. When I close the trunk light stays on. Any ideas?

Mercury switch holder is not holding the switch correctly. It needs to be adjusted so that the top points slightly down when closed so the mercury inside breaks the circuit.

Could also be that the lamp housing/mercury Holder is gone bad?

Easy to test the switch. Simply remove it from the spring clip holder and rotate it while checking the continuity between both leads. If it makes and breaks (as reliable as gravity if the mercury is still inside the tube), it isn't the switch.

That’s why the mercury was not making contact

You are lucky! 9 out of 10 mercury switches of any era, even early 90s (such as k1500 trucks, etc.) don't work. And of course, mercury is frowned upon these days so the replacements are mostly purely electrical. But definitely keep an eye on it from time to time. If you start running into battery drain issues keep checking that trunk!
