Federal Signal Lightbar Nightlight

Hi, I recently removed a Federal Signal Vama lightbar from our old ambulance that is waiting to be scrapped and I was wondering if I could convert it to illuminate our garage as it would make a cool effect. I already wired it up, but now I am wondering how big of a resistor I would have to use in order to not burn out the LEDs and the power suply. there are 22 LED modules in the lightbar itself and I have a 12V 5A power suply.
Thanks in advance.

Best regards,
Andraz
