Those look like the same type of sealed lamp assembly I have on my coach.
I did not order...I picked up the Barjan equivalent LED at a Truck Stop.
Work great.
NOTE
epending on the turn signal flasher if you convert ALL your turn signals......(Front and rear) Bad things may happen.
IF it happens two choices
1:resistor (sold for that job) Get it where you get your LEDs
2: New flasher..One that is not number of lamps dependent.(HD)
