Front blinker bulb stays on??

[Rooster20]

My right front turn signal bulb filament stays lit all of the time when the lights are on. The side marker and the rear turn signal blink fast when selected but the front just stays on solid regardless if selected or not...as long as the lights are on both filaments stay lit.
Any idea on a fix for this?

The front, fender and rear turn signal bulb are all on the same circuit. I would check the front built first, it could be internally shorting since it is a dual contact bulb; marker light and turn signal.

New bulb. Old one did the same thing. :/

Pretty sure it's a grounding issue.

What makes you say that? The bulb being on means there's power and ground there completing the circuit. Test your wires with all three bulbs. Pull your marker and rear bulbs out leaving in just the one in the front and see if it still does it.

Are you sure it is the correct bulb? Swap the other side over. When I have seen this, the bulb was only a single filament

Yea it's the correct bulb.
Reason I say it's a ground is because a close friend of mine who's a head Porsche tech is saying that's very likely what it is.

There is a stud with locking nut on both side of the fender, right behind the headlight where all the grounds are run. Check there, and then I would check inside the housing of the corner lamp/bulb connector to make sure there isn't any issues with grounds

The front marker light should be a dual contact, maybe a 12v21w bulb. There should be a 3 wire connector for it, X137, pin 1 ground, pin 2 right front turn light, and pin 3 right park light.
