Topic: 50 Merc trunk light


Pete    -- 02-26-2011 @ 6:56 PM
  Recently acquired a very original 50 Merc Sport Sedan and am fixing the many little things that don't work. The interior trunk lid has a courtesy light that is supposed to activate when the lid is open. I cannot find a switch of any sort that activates the light. Is this a mercury switch of some sort or a mechanical button switch that I haven't located yet? Tested bulb and wiring up to bulb and don't know if I have to dig deeper for fuse or what ever.

  Did you turn on the parking or headlights first? I don't have the schematic but the trunk light most likely is powered through the light system. Ken

  The accessory trunk light that came with my '47 has a mercury switch built into the base, and was wired into the license plate light circuit. It worked with some persuasion, but I wouldn't trust it without a master battery shutoff switch to be sure it is off when the car is parked. The wiring to the light was crude, so I assume some owner, sometime, found the light and decided to add it to the car and tapped the nearest wire.

  My 1940 Mercury has the trunk light switch attached to the hinge. This was a stock item on Mercury for many years.

It is controlled by a mercury switch and powered from the light switch on the same circuit as the tail lights and rear license light. I would assume that your 50 Merc is the same. I don't have a wiring diagram for the 50.

  I have a47 monarch Canadian made with a similar trunk light mine doesn't work but it is wired to the park lights so they have to be on . Also look to see if the bracket has two holes they are for adjustment of the Mercury switch . I'm planing on hiding a switch to turn the light on .

  I have a 1950 Sport Sedan with the factory OEM white bubble trunk light and it always was connected to the park/tail light wiring. If the tail lights are lit it is on. I didn't realize this little white bubble light was factory until I got an accessory brochure.

  If you have somthing prehistoric looking on your rear package tray that is a factory rear speaker. Your trunk light should look like this.

  Nice original car 56Markll... Can you please do me a favor and measure the bottom of your steering wheel to the top of your seat cushion on your original car for me please? I think that mine may be over stuffed? I only have 4"s. Thanks in advance! Randy

  Sorry for the late reply!! I thought about that but as I posted to your other thread my seat is sat out with a blanket thrown over to hide the carnage and a rag packed in where the sponge used to be to pad the springs lol! Yes I have to get it re-upholstered! Is it sitting in the frame properly now that I see the cushion just sits in there?
