I recently installed some LED turn signals in the front. When I switch the parking lights on, only the right side comes on. The crazy thing is, the left side comes on only when I use the turn signal. When I turned on the emergency lights, it was flashing but from on to completely off instead of on to dimmed like the right side. Any ideas?

 

Do you have switchbacks or regular amber led turn signals?

 

They're regular. I'm starting to think they might be polarized, but if they were, would they come on at all if they weren't facing the right way?
