Sorry no pictures but some points.
What do you want?
If you are after a simple but significant driving light go with HIDS - either dump you stock lamps and instal legal HID replacements or add an extra set of low-level HID driver's lights. In most states/provinces depending on what lamps you choose, these are not classified as off-road lamp positions, don't need covers and can be used whenever you need them.
If you are really talking offroad then things get much more fun! You can go low with a single or big pair of real off-road spots and or go high with a light bar. If you are planning to do night-time gnarly offorading you may want to have two angled high sidelamps to cover corners better and high reverse lamps for getting out of trouble better.
If you choose to go high-mount, watch out for hood glare; light reflected back in at you. Careful positioning of the light bar and aiming the lamps makes a big difference.
If you buy Lightforce or Roolights (lightforce knock-off) you can buy a range of filters that can alter the colour and type of beam depending on your driving conditions.
Check your regional laws regarding lamps. I have to have all my lightbar lamps covered here in BC on regular highways.
