Amazingly bright and very well manufactured.

The brightest solar light i've purchased yet, i've purchased quite a few solar light and this by far is the best, i was pleasantly surprised by the amount of light this gives straight out of the box with absolutely no exposure to sunlight at all. For under $100 that can't be beat, i'm quite please with my purchase, hopes the longevity pleases me as much as the lighting it provides, considering getting a couple more. Great light.

Much brighter than I have seen from most LED strips.  Really well made.  The sticky tape isn't any good, but some 3M tape took care of that.  I have them as footwell lights in the front of my truck and one on each side of my truck bed.  Really bright under the tonneau cover.  Ordered another set.

Extremely bright and I like the fact that you can narrow the beam.

Really impressed by this taillight.  With the singled LED, I was a bit worried that the off axis lighting would not be up to par.  But Blackburn did a good design with this one.

First is the ultra bright LED.  The LED's built in lens directs a really bright beam straight back, about 20 degrees wide.  It is so bright that I wonder if it irritates some drivers.  20 degrees doesn't seem like much but it should be enough to catch the eye of drivers approaching off to the side from behind.

Then comes the way Blackburn mounted the single LED.  They pushed it forward into the outer red lens and surrounded it some light steering plastic so that the light coming off the side of the LED is visible from almost 90 degrees.  The single LED outputs so much light that the light coming off the side looks as bright as some ordinary LEDs straight on.

The amber LEDs on the side are no slouches when it comes to adding visibility straight off the side.  Not the incredible brightness of the main LED but they are pretty good, a lot better than the amber LEDs that Blackburn uses on their Voyager 4.0 headlight.

Mount is a little tricky.  The design is like a plastic hose clamp that you tighten with a thumbscrew.  But it works.  You'll also need a philips screwdriver to set the vertical angle of the tailight.

Overall, a very impressive taillight.

Very bright and well made. Bought a second one as well. One for the house and one for the car.

Wow. These lights are great. Very well made, easy to install, and produce a nice, bright spot light. There's enough light spill to light up a larger area, but the point you aim these really gets a lot of light.  Top be honest, I was going to put these on the bumper on our SUV, then decided to put them in the back yard on a motion controlled landscaping timer. I have them mounted on the deck, one aiming at each gate. When someone enters the yard at night (something that should really never happen, as we use the deck), both lights turn on and nail the gates with a bright light.

Yea, I know these are designed to be used on a vehicle - but there's nothing like it for yard lighting - plus have you seen the price of good quality yard lights? Yes, these are fantastic on a vehicle, but for the price they can be put to other uses as well!

Since these draw so little power, they would work on most 12V power sources. Vehicle, motorcycle, yard light transformer, etc.  I'm even thinking of picking up another pair to put one on the shed, also motion controlled, powered from a battery that has a solar charger.

I took a chance as there were no reviews anywhere I could find on these and I am really impressed.  The mounts are solid and the wiring is good quality with a lighted rocker switch included in the package.  I added a relay that is triggered by my bright headlight wire so that they can only be used when my brights are on.  These lights are so bright, most definitely illegal on road as you can see into the next zip code with them on.  The light is bright white and you can see bugs in the air for a half mile it seems.  I have only run them with the clear guards on them, not the amber so I have no comments on the amber covers.  But these are fantastic lights that I'd recommend to anyone who is looking for HID's that are affordable.  I drive on country roads that are teeming with wildlife and have had many close calls so I am looking for an advantage when driving at night and I'm pretty sure these will more than do the trick!

Just don't forget you have these on if you use them on the street because I'm pretty sure they would blind oncoming traffic.

These are super bright. They do run a little hot, but with that much light output, I don't think you could do anything about it.

Very impressive and so far I have about 40 hours on them with no problem.

extremely bright light and very well made.  Good value.  and uses regular AA batteries, so not overly expensive to maintain

This pair of lights are very bright. I used them for headlights on my three-wheel recumbent bicycle  - one for the high beam and one for the low beam - and they are as bright as car headlights. You can see in my photo how bright they are!

They are also very solid and rugged, and well-constructed of good quality materials.

These lights are incredibly bright!

I wish they made these for my other vehicles as well.

I was very impressed with the box and packaging containing this product - first rate all the way.  The product itself is everything I hoped it would be.  The light is very bright and adjustable and fits comfortably.  My hope is that it will last over the long term.  I have too many flashlights over the years that mysteriously either stopped working altogether or worked intermittently - apparently bad or poor switches, etc.  This Xtreme X55 seems to be very well made so I am optimistic.
I was also impressed that the company sent an email to follow up on my order and to invite me to contact them with any questions or concerns.

This taillight is bright. Really bright! Almost blindingly bright in flash mode. Of course, there are other taillights on the market that produce a bright flash, but what makes this one stand out from the pack is that Cygolite has finally developed a taillight mount that is just as secure as its headlight mounts. The brightness can be turned down in the steady-state mode so as to not blind your fellow cyclists in group rides at night. I wish it were also possible to adjust the flash brightness, as the light is far to bright to use in flash mode in group rides, but it isn't. The flash frequency is continuously variable however.

Other reviewers have pointed out that the light's beam is narrow, and it is, but I find it plenty wide enough to be seen by drivers approaching from the rear.

The light has a non-removable internal battery, which is charged by means of a mini-USB cord. The cord comes with no charger, but it can be plugged into a computer to charge the light. I have so many devices now that charge either through mini- or micro-USB cables that I already had several chargers, so that was not a problem.

In conclusion, this is the best of the bright taillights that I have tried, and I have tried all of the major competitors. The new mount is secure, and the flash mode is very bright. If I were asking for perfection, I would like a slightly wider beam and a way to adjust the light's intensity in flash mode.

Incredible light, very well made with quality materials and tooling.  Browse through the manual (online or paper) and familiarize yourself with the operation.  One of the best lights I have ever purchased.  I'm a believer!
