Will these fit my Hino without any modification?

Yes. These mount at factory rocker points with no drilling, brackets, or adapters needed. Just bolt them in place using existing hardware.

Do these come with bulbs installed?

The assemblies ship as-is. Install your own bulbs before powering them on—refer to your truck's service manual for the correct bulb type and wattage.

Is there prep work needed before installation?

Inspect mounting points for debris or corrosion and clean them. The black finish is ready to bolt on; no sanding, priming, or painting required on your end.
