Denali LED Review

Hello all.

I mounted a pair of Twisted Throttle Denali LED lights a few weeks ago and felt the need to write a review of my experience with them. They were mounted on a TT light bar next to the factory lights.

Quality appears excellent. The wiring harness is basically plug and play. I wish they would include the switch mounting plate or at least make the recommendation you purchase it. I did not know it was needed or even existed until after I received the lights. It only costs $ 6 so if you order the lights get one.

As for the light output:

I ran them with the spot lens, not the fog. They have a 15* beam on the spot lenses. I tested them on darker roads with little or no street lighting.

When mounted and adjusted at an angle under the stock low beam, they still blinded oncoming drivers at night. I figure this was due to the 15* beam, but I could be wrong, it may be due to the brightness. They are bright!

The light emitted is very white and renders the roadway very clear at closer distances. The Denali's fill in all the gaps from the stock lights (on low beam) and the light travels a bit past the low beams.

I adjusted them a little further up and they performed just about the same. At an angle similar to the high beams, you really do not get any further down-road lighting. They still illuminate the road clearly (at closer range), but their distance does not reach the distance of the stock high beam. At any angle of adjustment, I was not able to match the distance of the stock high beams with the Denali's.

I was disappointed with the throw of the lights. I wanted them to illuminate the road at longer range, but they did not do that.

No matter what angle of adjustment, I felt I was over-driving my lights at 55 + MPH. I needed the stock hi-beams to make up for this.

For off-road driving or illuminating the roadway at lower speeds they work great. They also give you more peripheral lighting and light up street signs, but again at closer ranges.

The main reason I added the lights was to illuminate further down the road for those times you get caught out after dark and want to see far ahead. The Denali's were not up to this task.

I wonder if a narrower lens beam, say 8 - 10* would correct this issue or is it that an LED just isn't going to give you the down road lighting of an incandescent light.

I hope this review helps anyone looking for auxiliary lighting.

Thanks for being the guinea pig. I agree, the best use of driving lights is to light up the road well beyond the stock high beams. I've been looking at Trailtech HIDs but they are very spendy as well.

I put HID's on mine but didn't like the light distribution. Then I put a pair of Phillips xtreme 80+ bulbs in and it makes quite a difference. I also used the harnesses I bought for the HID switching so I am running the lights directly from my battery and using the stock wiring as a switch. They are halogen so they work with the reflectors correctly and they really are considerably brighter. I'm not saving the 15 watts per bulb I had hoped for but I do have great lights.

I was wondering if the wiring harness for the lights actually did anything. I guess it does. Did you measure the voltage between the stock wiring and using the harness? I am curious to see if there is a noticeable difference on a digital volt meter.

There is about a 1V difference between using the stock wiring to light the bulbs and using it to throw relays to engage good size wire without a bunch of connections. It's noticeable.

LED lighting at this time does not put out the light output (measured in lumens) of halogen or high intensity discharge.

As usual, you are right on. I just tested my headlight voltage on the left headlight harness with the ignition on and motor off. It was 11.09 volts. I unplugged my Denali's and turned the switch on. The voltage was 12.19 volts at the Denali harness. At the actual battery was 12.32 volts.

I will order a harness from Eastern Beaver.

Hey Guys!

I'm just now installing the Denali wire harness. Mounting lights on fabricated brackets, clamped on upper engine guard.

Wish I would have skipped getting the harness and taken the time to make my own. Your right! Relay should have been up front.

[Where does the WHITE wire go ? ] (edit) DOH ... When in doubt, read the instructions ... white = switched power wire

TIA

I would actually argue the point below.

I picked up some LED floods from a guy on ADV (also available on fleebay), and at a recent meeting of riders, we compared mine to the TT Denalis. I won by a landslide. Maybe the tech is getting better, maybe these LEDs are just configured better, but they rival, if not match the output of my dual HID headlamps. Its like frekkin daylight in front of me
