I have the version without the angel eye. eBay for $90. Looks like all these lights no matter who sells them are made by the same factory in China. Ditch the star washers that came with it. Had the same problem with mine. Without the washers you can get it tight enough where it takes a fair amount of pressure to move it. It will never be as tight as the stock one was. As far as brightness, the 4 single D shape lenses are your low beams and the circular ones are your highs. When I shine the bright against my garage it looks more like a spot light but on the road at night it works great.
Use some blue Loctite on the bolts that hold the light onto the bracket.
