    I take it the new offroad lights are rated at 50 watts or greater.
    A toggle switch mounted to the dash and wired to the fuse block will either end up causing an electrical fire or won't work for long.
    The proper way to wire up any high amp accessory is to use a relay.

    Here is how to do it properly.

    The "86" connection is a dash mounted switch that goes from the fuse box.This will be a VERY low amp draw source.This will trigger the relay and allow the full,high amp currant to go through the relay,directly to the lights.(much safer)

    The "87,to the devices"connection will go to your new lights.

    Hope that helps.
