I've been using the trailer for about eight years and have replaced these ballasts five or six times in that time. As an electrical engineer, I see that this project has not been updated since humans used computers to design circuit boards. The quality is poor, the price is relatively high for what they are. If I had another option, I would take it. LEDs are beginning to get bright enough to be a viable replacement that doesn't require a ballast at all. I buy them because they're easier to design as replacements, not because I think they're high-end electronics.
