I recently picked up a set of the KTM LED aux lights for my 990 SM-T and got them installed a few days ago. Installation was a bit time consuming but straight forward. I really like that the kit does not require splicing into the existing wiring harness and that the kit replaces the original start/kill switch on the right handlebar with a new switch that has the start/kill & Aux light switch. This makes for a nice clean install. With the Aux switch you can set the Aux lights to be on at all times, with hi-beam only, or off. I plan to use them with hi-beam only but it's nice to have the options. I opted for LED for their long life and also for their reduces power requirements.
These LEDs have 3 intensity settings that are controlled with a waterproof push button at the rear of each light. I set them to high and intend to leave them there since I will be using them with my hi-beams. It would be advisable to set them to one of the lower settings if you plan to use them at all times so that you aren't blinding people at night. They are pretty bright but more importantly have a wide dispersal pattern so it would be very distracting to others if you left them on high and had them on at all times.
When I am thinking about purchasing some new farkle (especially pricey ones) I like to get an idea of how it will perform before I spend my money so for anyone else that might be considering these lights I took the pictures below with the bike in a fixed position, the camera on a tripod and the exposure & f-stop set to manual in an effort to supply a realistic idea of how they perform. As you can see they are not a long range focused beam, rather they act as a hi dispersal fill light. This works extremely well for the types of roads I tend to ride. It improves the ability to see the road in corners and also does a nice job of adding light and contrast to the road ahead of the bike so one can spot stray gravel washes and such much better.
Anyway - enough talk - here's the comparison. Again, no trickery. Nothing moved between shots and all three shots taken with the exact same camera settings. After all, I'm not trying to sell anything, just trying to supply an honest comparison.

Low beam/no aux lights - Good light pattern close to the bike with the typical sharp cut-off which can be so troubling to cornering.

High-beam/no aux lights - Decent reach forward and not terrible fill but not great for road surface detail at speed and could be better in the corners.

High-beam/ aux lights on - Provides good fill light and because of wide beam does a nice job of lighting up hilly & twisty sections where the stock light alone would leave me wanting.

These are not the lights you want to run triple digits on a dark interstate due to the lack of reach but for getting around twisty blacktop and gravel roads at night they do a very nice job.
