So after almost a year of usage, the issue where the LED in the corners of each DRL either flickers or goes out completely started occurring on my set of headlights so it was time to submit a warranty claim.
I worked with the original vendor (HID Kit Pros) to start the process of replacing the set under warranty. Once I was transferred over to Morimoto, it took 3 business days to receive the advanced replacement set. I opted to pay a core deposit for the advanced replacement as I didn't want to send in the defective set first, reinstall the stock units, then repeat the process when the new lights arrived. The core deposit was reasonable and I did receive a Gen2/V2 set of headlights as the replacements which is consolation for the time spent.
Contrary to the bad experiences some have reported in dealing with warranty or RMA, my warranty replacement was as smooth as could be. Morimoto was super responsive and I think the process took a total of 5 calendar days from start to finish with two of those days being the weekend.
My impressions -- The Gen2 headlights are what the V1s should have been. Although the V1 headlights were better than the stock units, they weren't perfect. The Gen2 no longer projects a spotlight-ish beam pattern and the dark spots at the corners are gone. I could go on about how much they've improved but the pictures may do all that. The lateral illumination is much better.
Overall I am quite happy with the replacement lights. I just hope this isn't an annual drill. At least there are 4 years left of warranty if anything goes wrong.
