Just wondering, why the full light bar? Not saying you can't have it, but if you are looking for something that you can take back off I would personally go with a mini-bar that is mag mounted. For the price and the headaches you would get off of buying a knock off bar like this one, you can get a decent priced name brand LED mini and would serve your purpose very well.
Again, I am not basking you in any way, but most people don't have good luck with knock off bars. And there are lots of good mini's out there now that are just wonderful.
