I installed them on my trailer for safe lighting and warning. At first I was happy and satisfied with the purchase, but after a month the waterproof seal failed and the headlights were filled with moisture from constant rain on the streets. But the light worked so I didn't mind. Shortly thereafter, I worried that the light was wrong. They dimmed where they were barely visible, and a few days later the other light didn't flicker. Shortly after, I emailed asking for a refund or exchange and haven't heard from anyone since. I wouldn't recommend them because they don't live up to what they promise.
