In the last decade, there have been more advances in 12V technology than in any other area in the 4WDing world. Some of the products that are available cheaply these days would have either cost a mint, or flat out didn’t exist not too long ago. Both input (batteries and charging systems) and output (lights, in-car entertainment, GPS) accessories have absolutely exploded in the last few years and these days you’d be hard pressed to find a touring 4WD that doesn’t have at least a few 12V upgrades.
However with so much choice now available, it can be difficult to know where to start. Over the next few pages we’ll show you what it is, what it does and why you need it! If you do any sort of driving after dark, your 4WD’s stock headlights will come up short in terms of distance and lighting up the sides of the track where animals seems to always lie in wait for the very last moment they can before jumping out in front of your bullbar.
