Cateye Vectras on multiple bikes, all dynamo hubs and lights, zero interference from the lights. Max speed errors are so frequent and common that the values are useless. Well, I’m pretty sure I’m not hitting 68mph on my ride home. Not sure what causes the errors but it happened before the dyno too. Occasionally the speedo will read “0” as I pass through intersections. It’s brief, happens only through intersections, and not all intersections or even on the same intersection all the time. I don’t worry about it. I accept these things as part of the cost of wireless.
