Denali D4 Flood & Spot Hybrid LED Lighting Kit
Great lights - love em...cheap switch - meh.
I love the lights...they are very bright. Unfortunately the switch is very cheap and the outer housing popped off the other morning while riding to work. Now I am left with a printed circuit board flapping in the wind. Undoubtedly warranty service will make it right. Even then, a great product, the lights, will be unevenly matched with a cheap switch.

Like day at night...
Lovin' these lights. Far brighter than the high beam on my bike so I won't drive behind someone at night with these on but I hooked them up so I could switch them on without the high beam and have them on during the day. Sure get noticed more which was the whole point. A little bit fiddly to install but that was more about my bike, these lights are basically plug and play. Put them to the test coming home late from work, switching between them and the standard bike lights was like night and day.

Let there be light!
I've had the Denali D4 lights installed on my GS for a year and a half. In that time, I've had no issues with the operation or quality of the lights. The lights have held rock steady in the position I mounted them and work as well and reliably today as the day I installed them. So, for function and reliability these lights get a solid A+ from me.
I purchased the mount for the water cooled GS, and the installation went relatively quickly and easily. The only challenging part for me (and this really has nothing to do with the lights at all) was finding a good spot to mount the relay. The kit pretty much included everything I needed to do a professional-looking, secure installation. I do have one thing I'd put on my wish list, and I talked with a Twisted Throttle rep about it. For the R1200GSW (which I have to think represents a pretty sizable chunk of the D4 market), you cannot control the lights with the bike's high beam switch because the high beams aren't voltage controlled. They run off a CanBus, but the relay needs an analog input from either a conventional high beam switch, or you need to use the dedicated switch that comes with the D4s. Incidentally, the switch mounting plate isn't included, so plan on ordering one when you order the lights. The left grip on a fully equipped GS is a busy place already (see photo below) and I couldn't find a likely mounting spot that wouldn't interfere with other switches. The kit includes a longer bolt and spacers meant to replace one of the rear view mirror/brake reservoir bolts. Even the longest is slightly too short to clear the switch plate on the right grip, so I have it angled slightly down (photo below). It isn't awful, but it means I have to move my throttle hand somewhat awkwardly to activate the lights. I haven't found a longer bolt with the right threading yet, but will easily fix the problem when I do. This isn't a huge deal, but I have to dock a star because of it. This wouldn't be difficult for Twisted Throttle to create a model-specific kit for, but the ultimate fix would be for them to engineer a harness that allows using the bike's high beam to control the D4s. Take note that if you have a "normal" voltage-controlled high beam, the D4 relay can be easily wired in and activated whenever you turn on the high beams.
So, how do they work? Um...WOW! I bought these lights after riding Rt. 33 from Virginia into West Virginia around 10 P.M. one fine summer night. The GS has a phenomenal LED headlight, but that doesn't help you see into the turns since the light stays pointed straight ahead. Hairpin turns on mountain roads in pitch black darkness aren't my idea of a great time. The D4s greatly solve the problem with their bright, wide dispersion beams. They simply turn night nearly into day. They don't reach quite as far straight ahead as the stock LED headlight, but that's not a knock on the D4. They aren't intended for that, but would easily out distance the headlights of every bike I've owned prior to my current ride. If you don't have an LED headlight, I absolutely guaranty the D4 will be brighter and throw the light farther than your headlight. The beam width takes the mystery out of turns at night, so they do exactly what I wanted them to do. One last thing; I really DON'T recommend these as daytime running lights. They are too bright for that.
All told, the Denali D4 is a fantastic product. The only knock I have on them is one specific to my make/model of bike, and not on the lights themselves. I highly recommend these lights without hesitation.

Excellent Product, Awesome Performance
I purchased the Denali D4 along with the Denali DM by reading reviews like this, and I will have to say that I am more than happy with these products and are happy to recommend them. I have mounted these lights on my V-Strom, they not only look good but perform well too.

Denali D4 lights
They are super bright which add to safety during the day for visability and awesome at night with the flood and the spot light. They look great on my BMW 1200GS. Less then half the price of stock BMW lights and twice as good

Denali D 4 lites
They provide extra long distance lighting as well say great spot side lighting
Be careful of the touch dome on off switch.
IT POPS OFFICE EASILY
I added a small strip of clear tape as a safeguard.

I've Mounted A Small Sun To My Bike
I bought these to go on my bike for better daytime visibility and better distance at night. These are waaaaay too bright to run at night if you're behind another car. I want to be seen but not cause a crash. I tend to treat them like my high beams at night and they are brilliant for that. I run them constantly during the daytime.
At night, these light up dark roads like the sun was still out. No one can believe how far they throw light and how wide the beam goes as well.
The only thing I would change is to give them two brightness settings so that I can run them when I'm behind other cars.
