They do not meet US Dept of Transportation specifications. If they did, they would not work so well.The E-codes say they are not dot approved which confuses me.
They were good. As good as these Hellas I guess. I had one take a rock on the road and broke so I went for the Autopal (cheap). I think the Deltas are now a lot more expensive than the Hella.How did you like the Deltas? I've been looking at them.
