[MENTION=79761]Cycle M5[/MENTION] sorry to hear of your woes. Thanks for documenting your experience, but I would've returned them before soldering, trimming and whatever. I'm sure any "warranty" claim would be thrown out the door. In any event, good to see you got them working. Your experience is WAY different from mine. I had no installation issues and they continued to work flawlessly even when (a few threads ago) one popped out of the light assembly. It got soaked, frozen, etc and continued to work. I'm still happy with them and would recommend them to anyone.
Switchbacks (lots of chinese products) have been out for a while now, but most folks get them on fleabay. I still say vLeds make a quality product. I haven't seen a product that compares to them (in fact, I'm playing with the idea of getting their LMZ 4500LMN monsters for my hi beams). If there is a company that stands behind their product like they do, let us know!
Let us know how they hold up!
