Been too long! How do I remove a burnt out turn signal bulb?

The left front turn signal on my '65 Dart doesn't work. The other three blink quite nicely. So I figure a burnt out bulb. I remove the amber lense and try to remove the old bulb. But nothing is happening.

If I recall right these old style bulbs don't screw in or out. There's a trick to them but my memory is hazy.

Do I push on the bulb a little bit and turn to the left or to the right? Or am I way off base?

Help!:?
