Getting a Grimes & Whelen strobe to work

Does anyone know what is needed to run the 2x Grimes bumper strobes & the Whelen roof bar strobe? Car battery is 12v, the Grimes both run off 14v DC (2 amps) & the Whelen 28v DC (1.6 amps). I’ve been looking on eBay & there appears to be power supplies available but just wondering how others have achieved it. Thanks

I run a Whelen power supply to power my Grimes strobes since I removed the lights from their power supply. The Whelen HRDF has its own power supply as part of the entire piece.

Ok, so I have two grimes 30-0504-1 lenses & two grimes 30-0437-1 strobes. I thought the lenses sat on the strobe units, am I wrong?

And the Whelen HRDF, straight hook up to 12v car battery?

What whelen power supply do you run from a 12v car battery to power the grimes?
