Just a quick video of how bright my light bar on my 2007 Subaru WRX is with 4 Hella 500 lamps. I show them turned off on my house and then turned on. They need to be re adjusted. Through washing the car constantly the lamps are now not aiming completely the way they need to be. The top 2 lamps are aimed up so that the tops of hills are illuminated and I can see what is at the top before I even climb a hill and the bottom 2 are straight ahead to illuminate what is directly infront of me.
