Good product.
The bulbs are good. The packaging would be a challenge for a roadside replacement without scissors or a sharp knife.

Bulbs aren’t the same size
Ordered these because I needed both bulbs, when they arrived the two bulbs were different and only one fitted into the holder, one was correct but one was smaller and the metal tabs didn’t line up
