Head light delete

[PSI 800]

I put a headlight delete kit on my 2015 PRO 800 and want to install an LED light bar on my handle bar for better light. Question is do I need to put a resister in the power lead so that I don't fry the LEDs and if so, what size? Thx in advance as I don't want to fry my light bar

Probably need to rectify to 12V DC, I know earlier sleds (dragons) use AC to power the headlights. And don't overdraw, meant to power 2 55 watt halogens...
