Halogen to LED switch

Hey I have a 2011 Prius, have had it for about 2 years and STRUGGLE with the halogen headlights, I wanna switch to LEDs (probably for both low and high beams)

Saw a post about this that’s been archived so making a new one with some questions that I didn’t see answered there.

For the 2011- do I need to replace the entire housing for this switch? Are the low beams and high beams separate bulbs?

The lens is clear, some moisture in there from when I BOUGHT the car, hasn’t gotten better or worse, but, doesn’t seem to be the issue. I have replaced the headlights multiple times because the casing burns up over and over again, (have had that happen twice)

Looking for recommendations on LEDs that’ll fit my car and any tips from anyone whose done this in the past

May edit with some other questions later but thank you!!
