loud exhausts save lives...

The lights are only 10W (you can get much much more powerful ones), same as the cyclists use these days and are at around the same height off the road as mounted on cycle bars. They are more eye-catching than headlight simply because they are more compact (higher light density) and have a very blue/white output - plod has never shown any interest in them. They are pointed down and towards curb side of road, but still are very visible from head-on.

10W LED are MUCH more powerful than anything halogen. If they are the 8000 Lumen items you have the equivalent of about a 400W halogen lamp!

Decimal points are in the wrong place, they are about 800lumen (about 40W equivalent halogen) - you can readily get 1000 - 1500 lumen LED lights for push-bikes these days.

In perspective the HID headlights on that SUV shining in your rear view mirror are at least 3000lumens each (can be up to 5000) and are very blue, a colour that your eye is very sensitive to (especially in the dark), that is why HID headlights are soooh annoying (that plus the fact that the self leveling mechanism never seems to work and the beams light up the roof lining of your car).
