So, regarding the rear bulb assembly in 97 vdp, if someone were to, let's say, put a 'p21w' base bulb in a 'pY21w base' bulb-socket, it can get stuck, you may wonder how I know this.
I found that the pins that hold bulb in place on the ...

• 'PY21W' are offset to one side (150 degrees) ,
  • so turn signal bulb socket is meant for (150 degree) bulb.
• 'P21W' pins are straight across from another (180 degrees).
  • it is easy to get that wrong bulb in to that socket
  • getting it out is another story

I have twisted, pulled, pushed, and jiggled, but do not want to force it (until it is hope is gone).
Any ideas?

 

Potato method . but this would require breaking the glass bulb , after broken a set of needle nose pliers

You can grip a intact glass bulb by slipping over a sized nozzle like on a bathroom caulk sealant cartridge / tube

 

So, whilst twisting and wiggling, the glass bulb part separated completely from the base (without breaking). I first thought oh sh*t, but then, I was able to then bend the thin base metal with a pair of needle nose and remove. I've never thought of doing this on purpose, but It's a good option to know about.
