That's new to me.

Looks like pbsf is better, unless side visibility is so important to you that you're willing to compromise rear visibility.
My vetta is significantly brighter than my 2 x pbsf.

I think this makes vetta the reigning king of low budget taillights.
Cost unlimited, dinotte is still brightest.
Anyone happen to know the power supply for the newer dinotte 400R twin led taillight? It takes a dinotte Li pack, which they would only say in an emailed answer is "proprietary".
Anybody own a dinotte 400r and a voltmeter?
