OK, so I've had my JW Speaker model 8790 Adaptive LED Headlight for over a week now and have put it to some rigorous night-time use. Here are my thoughts on its performance. It lights up the corners while leaning really well -this is a really well designed light. It lights up the relevant corner evenly with the limit of the light just shy of the horizon - top marks for design! It works just like in the video of which there is a link at the bottom of this post. There are plenty of lumens both on low and high beam. Speaking of high beam - it really cuts through the night and lights up for a fair ways down the road - good! After my heated seat this has to be the best accessory I have ever put on the bike. It was a little pricey at $1320 AUD with $85 AUD fitting cost - but it was worth every penny in my book. It was largely "plug and play" with the only alteration required being a wiring adaptor harness which is stocked by HD. I recommend this light to anyone looking for better performance from their LED headlight. I am confident this will be the last 7" headlight I'll ever have to buy for this bike - it's that good I can't see the design being improved upon any time soon!

Looks great, aprillia and a few Euro bikes now have a seperate light that comes on while you corner. The price is a little concerning for me at this stage.
