This is an outstanding compact combo light bar, incorporating 40 CREE 3-watt LEDs in a double-row light bar. It is almost 2 feet long, including the mounting brackets. It is very bright indeed! It is great for operating your vehicle off-road or in extreme conditions. It is on my 4WD truck front bumper/grill and really makes a big difference. You could roof-mount it as well if that is your choice.
Please make sure it is never activated while on-road, the brightness is likely to blind oncoming drivers. My suggestion is to connect it using a lighted switch, to remind you that it is powered on. Highly recommended!
