I've been very happy with my Hella 4000k Cornering lamps. The light throw is perfect for night time trail use. 1M, 2M or 10M candle power is irrelevant if it doesn't light up the area you need?? Unless you're a desert racer, I don't see the sense in Euro or Pencils. The cornering is very wide and lights up the trail so I can see everything important. Mine are bumper mounted and flared slightly outward. On high mountain hwy passes, I use the 4K's with my high beams. It's the best of both worlds - I get great peripheral for deer and critters as well as awesome factory high beams for the long distance. I tapped into the factory harness and now my light switch activates the 4K's when I pull it out. Also, the orange icon on the instrument cluster turns on or off so I don't forget they're on.
