As the title, the left one keeps blowing after a few days. Anyone had this problem before?

only reason it would blow is over voltage, so check with a meter.
But the car runs on 12v so thats the most it should be, but test with car running, in case it is somehow getting alternator voltage of around 13.9v. ???
try LEDs which are less prone to blowing, and look nicer and brighter too

Ive been out to investigate and it turns out the plastic bulb holder is possibly not fully making contact. I pulled out the contacts slightly to get a better connection and didnt change the bulb and it worked, so if it happens again ill get a new bulb holder, but hopefully that wouldve fixed it?

I did notice the whole area was very hot (just got home) including the bolts that hold the light in so im wondering if heat is affecting the relativly soft plastic bulb holder and distorting it slightly?
