SSL requests failing

In my test script I have these options

var options = {
      host:   'badssl.com', 
      port:   443,    
      path:   '/',   
      method: 'GET', 
      protocol: 'https:',
    };

and this code after the definition.

var req = require("http").request(options, function(res) {
    res.on('data', function(data) {
      console.log(res);
      console.log("HTTP> "+data);
    });
    res.on('close', function(data) {
      console.log(res);
      console.log("Connection closed");
    });
  });

However, I keep getting a code 400 reply "The plain HTTP request was sent to HTTPS port". There are no redirects at the server end and I have tested the same functionality with my own server, address http://www.xdb.fi/dummy.txt - with the same result.

The script seems to be using http, despite all my attempts to switch to https. Do I have two blind eyes? I have one semi-blind already :)
