Well over here, my friend sold my other friend some Piaas and he was given a warranty on them.
This was at Tweeter, who are also Piaa dealers. My friend who works at tweeter told me that Piaa gives warranties (lifetime?) for any light products you buy from them. Whether they burn out, dim, or anything else caused by the bulb itself - they will replace the bulbs for brand new ones.
Also, MTECPOWER from ebay, and many others, offer a LifeTime Warranty on MTECS. so after searching and deliberating, I am gonna get me another pair of MTECS.
