once i figured out what it was called, sourcing was easy: auto parts, walmart, amazon, ebay etc
if you can match the photo with the part as their design differs slightly (some have locking tabs,
gaskets, etc) even though they're still calling them H11. you want the one which is the
counterpart one you have to ensure fitment and weather resistance. of course, you can buy a
matching set from the get-go (both male and female) but I didn't want it to be a mismatch to
the other side of the truck so I hunted for a near exact match of this simple and inexpensive part
