I couldn't agree more
The price is outrageous, even more so the failure rate of the LED's too. The really bitter pill to swallow is that these can fail the second you drive out of the dealerships driveway from taking delivery of it and they are not covered by warranty because they are classed as "light bulbs". I think there is a gent in Melbourne that pretty much has a full time job just fixing these.
I posted up the link hoping Hazerg8 could have a look and see if he can do similar or improve with better quality LED's
In regards to the fitment I'm not sure. There is a large difference between the two lights. When I look at my VF SSVR back on with my VF GTS beside it to me there would have to be considerable modifications made to the rear guard and boot plus rear bar too so I'm honestly not sure how they have done it but I sure would like to know because it doesn't look easy to me.
