good point p2

the downside to led light circuitry is it can generate some electromagnetic interference, which can interfere with some wireless computers and other sensitive sending units. Try moving the computers sending unit farther down on the front fork or the led light farther away from it….or as you suggested use an ant+ or a newer wireless computer that shields led rfi or even a wired one. If you don’t want to get a newer computer then look for a light that has lower power draw led’s. they still work well for visibility and also gives better battery life. The higher the power the more interference with sensitive wireless computers.
