They told us that only a white moored light was recommended for paddle craft, and other lighting wasn't recommended because powered craft were required to give way to non-powered craft. In low light, full lighting could mistakenly lead other power craft to believe you were under power and fail to yield.
We got the bright pole light. A bright hand held spot, and marked the hulls with reflective tape. We also had airhorns on both yaks.
The light kits you mentioned aren't prohibited, and many like them. Fishing where we did around that channel, we passed. Lol. Wasn't worth the risk.
Between the lights and the solas tape, you can see the kayak is well lit...
