Blazing Light!
I installed the upgraded light on my 1983 Suzuki Katana 1100 last year and what a difference in light intesity compared the stock dull bulb. I did have to modify the rubber gasket at the rear of the headlight assembly for the new bulb to fit due to the extra bulk of the fan cage. The illumination for night riding is dramatic and the visibility during the day is a safety plus!

Cyclops 10.0 H4 Ultra LED headlight bulb
I haven't wrote a product review in a long time. I felt that my experience needed to be shared. First off, thank you Taryn for the awesome exchange on the phone. You provided stellar customer service by assisting me with my order. I received the Ultra the next day. The presentation of the package was secure and well done. The LED build quality is premium. Not even comparable to a cheap Ebay substitute. I installed this LED on my 2016 Yamaha XSR900. Something to keep in mind if installing on this bike... room is very limited already within the headlight housing. The ultra does stick out a bit longer than a halogen bulb and you have the additional wiring harness included with the LED. I ended up removing a plastic bracket that holds the stock wiring in place within the housing to make room for the LED and its harness. After reassembly and flipping the key, wow!!! This mod is worth every dollar. Night performance is exactly what I was hoping for, f**king bright with amazing reach. You see and will also be SEEN. Even in daylight, cars cant miss you. I'm impressed with your product Cyclops. The experience from ordering, to receiving, to performance was more than I was expecting. I recommend purchasing the Cyclops 10.0 H4 Ultra LED bulb if you are in the market for a premium plug and play LED that is extremely bright.

I ordered the Ultra in The Netherlands, and bought the rectifier straight from USA, because it was not available in Europe. For AC powered headlight on 50cc street moped with H4 35 watt Bilux reflector headlight (Rieju RS3 50 NKD). Installation was very easy to do, and a hughe improvement of light output on the road and on traffic signs. It is very bright and low beam gives a broad bundle on the road. Adjustment for the hight from the headlight was needed otherwise everyone would be blinded by this bulb. Cut off in reflector housing could be better. But satisfied with the result.

Let there be light!
I originally was hesitant because of the price tag, but I was frustrated by my lack of being able to see the road in the dark. My early morning commute has stretches of road with no street lights so its very noticeable when I ride through there. I ordered a pair of these for my 2012 Suzuki V-strom 1000. Install was very easy once I figured out the optimal order of installation. My only real complaint was no alcohol wipes or double sided tape for mounting the driver box was included. Thankfully I had some 3M outdoor rated mounting tape and brake clean handy. I was able to find a nice spot to mount the drivers inside my fairing. I did not have to do any re-aiming, and holy cow these are like daylight in the dark. Extremely bright! The cutoff if any at all isn't defined like a projector on a high end car, but it does still seem to keep the light low so its not blinding oncoming cars too bad, and high beams are equally incredible. These lights have amazing side lighting and throw down the road. I am very happy, I just pray they last a long time because $80 a pop would suck to have to replace annually.

It's a SUN for a headlight!
So, I'm writing this review right after my first night ride with this bulb installed, and the light it puts out on my '16 FZ-07 is near a religious experience. It transformed a headlight that was pretty poor into something that's basically a small star. Just in a small headlight sized package! There's wider coverage, and MUCH further distance that the light is thrown. Very, very minor aiming adjustments will be made, but overall. Hands down the one of the best (and easiest) changes I've done to my motorcycle. 10/10

No overdriving this headlight
I just wanted to thank you for a great product that I purchased in June. I just returned from a 6.5k mile trip to Yellowstone, and several other national parks and monuments. We traveled via US highways and stayed off the interstates as much as possible. I used the CIL-LED-10.0H4 Cyclops headlight in conjunction with the Kisan Modulator. The combination was flawless the entire trip and continues to operate as described. I believe the combination of the Cyclops and the modulator avoided a possible problem twice on the trip. We were delayed by the closing of a bridge over the Mississippi River and had to back track over 50 miles thus loosing several hours that day. As a result, we had to ride at night on some two lane roads that were rural and sparsely traveled and dark! Night Sky Dark! The high beam of the Cyclops was incredible! I had driven at night with it in Tampa prior to the trip but, there was always some residual light around. The two lane rural Missouri road was lite up like my firestick in my backyard! There was no chance of overdriving it. This was the reason for the purchase as I could easily over drive my original H4 bulb. My friend was on his 2013 HD Road King he could light up the road but, I led him on my 96’ Honda Pacific Coast as my high beam light would shine further down the road. The new Cyclops replacement bulb over my old original H4 incandescent bulb is night and day! Thanks for a great headlight! Regards, Howard

Best upgrade to make
So far I've intalled the 10.0 H4 LED bulb into my wifes BMW 650, my Buell Lightning, Yamaha dirt bike and now into my new 2019 Royal Enfield 650 Interceptor. Daytime viability is a huge improvement. I feel this safety aspect in traffic is worth the cost along. Riding in the dark is at least 4x the light.
