I was given the same ones as a 'gift' with my NightBreakers too.
They are fine - no problem.
You'll find they light one way, but not the other way round, so when you put them in the holders there's a 50% change of getting it right first time.
I very rarely drive with only side-lights but they are much brighter and more visible than the originals which are yellow by comparison.
I like them - they look pretty! :hippie:
