which new light has two strobe modes

I was on one last night looking through several light manufacturers: Coast, oLight, NiteCore, Fenix etc and one of the models had an option for 4hz strobe and 20hz strobe... Does anyone know which company has this? :candle:

I have used strobe once and that was when I had a flat tyre on my car and I used my four seven mini AA to keep the other cars a little further from me.
That was a a fast strobe and it had good effect in that situation but I think a slower strobe is more appropriate in traffic like about 4 Hz you are asking about.

Zebralight has a slow 4 Hz strobe and my Fenix ld40 and my Eagletac P20C2 has a slow strobe maybe about 2 Hz.

I would love to see a slow strobe (2-4 Hz) on more lights, it could be handy in emergencies.
Much more useful than "tactical" strobe and SOS.

Don't know the Hz, but the Eagletac D25 series has two fast tactical-style strobes (one is variable) and two slower warning-style strobes (one is dimmer), plus a beacon and couple of SOSs.

Nearly any Eagletac has 2 strobe modes
