This is what I got from Amazon. They are coming from China and are taking for freakin' ever to be delivered. There are many choices for the replacement bulbs. These have projector ends and are ideal for back-up lighting.

Glad you did the right thing and finding the driver... Some people feel entitled to extort others for more money. You say "******* Balls". I see it as him having NO balls what so ever. Balls=Honor in my book. You hold the honor, now he holds YOUR balls...
Finally clicked the link....
Dude those are just led tail bulbs....expect some effect for people seeing you, but zero for you seeing stuff...our taillights are way high off the ground and not even pointed in that direction
Also you COULD have spent 5 bucks more at any Autozone or Walmart and got Sylvania LEDs...
