Virtually every single device creates RFI. The FCC Title 47 Part 15 and 18 standards do not specifically address LED lighting.

The usage of shielding is the last step to resolve RFI. It is the most expensive, complicated and least effective option. The first step is to prevent RFI. The second step is to eliminate RFI at the source. Usage of shielding is the last gasp, for an incremental improvement.

Please identify bright headlights (3,000 Lumens or brighter) that do NOT interfere w/ a wireless bike computer. It is my understanding that this is a known issue.

I expect your light blinds other cyclists/driver so much, they have no other choice than stopping or looking away.
Seems that this light is only usable in the right hands or for nightride/trail/forest use.
On my ride this morning there were a half dozen instances where my prior experience leads me to conclude that vehicles would have cut me off, forcing me to grab a handful of brakes to avoid problems. Instead the encounters were courteous, w/o problems.

So far, in dozens of outings w/ the blinking headlight I have not experienced vehicles "cutting me off".

Add your vote to the pro cutting off the bicycle tally?

My limited nighttime operational experience revealed that the green illuminated indicator was an insignificant distraction. It was in-fact very useful to have this indicator that toggled to red when the battery was near end of charge.
