I have mine about 2.5 to 3" below the roofline. The bottom of the light is about even with the lower lip of the roof. The goal was to not have it blocking view out the windshield. If one is planning on bashing into branches, this isn't a good location for the light, or probably the roof either, for that matter! But I'm in Nevada, it's more likely to get hit at the bottom of the windshield as where it is. This is a Nilight 54". Claimed 312 watt - it ain't. (It seems common for sellers to inflate the wattage. Interesting, as wattage is a measure of volts X amps - and is only indirectly related to LED light output, normally measured in lumens. Lumens per watt is about efficiency. ) I measured actual power use at 220 watts, 16.5 amp current draw from a 13.3 volt source. Still, this light is very bright and has a wide pattern with flood lights at each end and spot beam through the middle section. Impressive. For $136 bucks, not a bad deal I think.
