Decided after seeing how useful a lightbar like this can be for storm chasing on a friend's truck. I broke down and bought a cheap one of ebay. This one actually - http://tiny.cc/lightbarebay. I went with the curved to get a better spread of light and to match the curve of the bumper better. The quality of that lightbar actually ended up much better quality than I expected. I still have 2 smaller spotlight led bars to add more coverage in the ditches to help light up deer and other animals. The main use of these lights will be for at dusk and after dark on dirt roads, which is where you end up storm chasing a lot. Nearly hit a number of animals at that time of day and this could help with that. Those roads can be difficult to see even without the animals running around.
I measured the gap in the lower air inlet on my 2005 Hyundai Tucson to be about 25", so I decided to settle on a 22" light bar due to the mounts. Turn out the one I bought was just small enough to fit. You will want to take your headlights out for the install. You can run the wiring right through the grill. I bought this wiring kit just to make the install a bit faster - http://tiny.cc/wiringkitebay. There are actually good option to run the wires through some rubber seals out in the wheel well and in through the firewall if you want a clean install. If you have the none 4x4 model like me, you should have plenty of spaces to put the switch in, like pictured below. That switch is for amber lights currently but I will be changing out that switch and adding others for the light bar and other ambers flashers.
Will be building my new camera dome and will be posting updates on the build soon.
