Had a set of Clearwater lights for years. Moved from old bike to newer bike. Recently had an electrical gremlin crop up. Fiddled with the wiring, no luck. Emailed tech support at Clearwater on Sat evening. Got a response within about 20 minutes. A few more emails over an hour or two and the problem was diagnosed and a replacement part will be mailed Monday. Again, all this took place on a Saturday night... Fantastic customer service. This is why these lights are worth the price. Kudos to Clearwater!
