Anyone using the Dinotte 400 daytime for night use?
The mean & dark winter is descending as we speak...and Santa wants to get agent pombero new lights to ring in the holiday cheer, and to keep him safe and sound as he rides from A to G.
Want to replace the 4 hotshots with a single taillight. Will go with Dinotte. Despite the warning, anyone using the daytime 400 for night riding? I want the baddest brightest tail light out there. Maybe I will figure out a way to keep the hotshots on there too.

You won't need the HotShots.
You could run the Dinottes on Low Steady if they are Too Bright.
I have two single Dinottes spaced 8 inches apart.
I run them on 5 strobe pause.
One is faster and they put on quite a show.
I say, Brighter is Better

Go crazy and mount one of these on your helmet. I did.
I turn it on and use it at busy intersections or turn it on when cars are coming out from side streets.

You could use the Hot Shots as Side Lights on your bike.

Nice! I agree that brighter is better. I'm thinking Dinotte 400 Daytime on the seatpost, keeping a Hotshot on the rear rack, and somehow mounting one on each side of the bike. I used to have one mounted on the rear of my helmet like you, but that helmet needed to be replaced and the new one doesn't mount at a very good angle...
Looking to also swing a dyno hub from Santa + supernova e3, move the Niterider 1800 off the helmet to the bars next to the Cygolite Turbo 740, and find something brighter than the NR for the helmet.
I want to be a meteor on the roadway!

After doing some research, it is said that the 400R throws a wider beam than the 400R Daytime. Is this true? A poster on mtbr believes it has something to do with the curve in the optics.
i am looking for the best taillight that makes the widest beam, so that the light can be angled slightly downward to create a red bloom on the ground. I decided to keep two hotshots angled 40 degrees off each other angled at the horizon as well.

Do you get any "legitimate" negative comments from other motorists / cyclists when you run the "strobe and pause" mode? After getting several complaints that my 140L was dangerously distracting in that mode (for nighttime riding), I switched to the "slow pulse" mode for nighttime, but do go to the "strobe and pause" for daytime use. In addition to my 140L on the back, I do also have a PB Superflash Turbo in strobe mode.
I used to just ignore people's complaints about my lights, thinking "more and brighter" had to be better, and hey, at least people notice me. But, one night my daughter told me that my lights were so bright and so distracting that she had to look away from me altogether when she was passing me that night in her car. She thought it was more dangerous for me if drivers can't watch me as they pass.
I kind of get her point. If a cyclist is lit up to the degree that they are too bright to watch, then a motorist isn't necessarily paying attention anymore to that "bright object". Or, if a motorist is so attracted to that bright / shiny object that he then is no longer focusing on the basic act of driving (responsibly), is that also unsafe? I kind of have the mental image of bugs flying into a bug light. All joking aside, in some states here in the US there are concerns about the increase in motor vehicle collisions (at night) with parked police cruisers that have their "bright / shiny" strobes going. Many people believe this increase in collisions coincides with the use of brighter emergency lights on these police cruisers.
So, anyway, not to get this thread side-tracked, but all of this is making me re-think how I am presenting myself on the road with lights, with headlights / taillights, and reflective materials. For commuting purposes, I am no longer of the "more and brighter is always safer / better" camp.

There is no academic literature to be found that supports the fear that super bright bike lights cause motorists to crash.

A quick Google search turns up multiple citations of concern about the intensity of headlights. Here's one, part of a report from the National Highway Traffic Safety Administration:
Characterizing Glare
Glare is a sensation caused by bright light in one’s field of view. Glare can reduce one’s ability to see, create feelings of discomfort or both. The term headlamp glare is defined herewith as visibility reductions or discomfort caused by viewing oncoming vehicle headlamps or headlamps in rear view mirrors.
Glare reduces seeing distance because it causes light scatter in the eyes, which in turn reduces the contrast of roadway objects. This effect is known as “disability glare.” The greater the intensity of the glare light and the closer the glare light is to where one is looking, the greater the disability glare will be. Disability glare can lead to the following effects:
• Decreasing visibility distance. The distance at which an object can be seen is known as the “visibility distance.” This distance is reduced when disability glare is present.
• Increasing reaction times. As the intensity of oncoming headlamps increases, drivers’ reaction times to objects in and along the roadway become longer.
• Increasing recovery time. After drivers pass an oncoming vehicle, the glare has a lasting effect that increases the time it takes for the drivers’ eyes to recover their ability to detect objects. During that time, the visibility distance is reduced and reaction times are increased.
As described above, headlamps can produce a sensation termed “discomfort glare.” This is the feeling of annoyance or even pain that is possible when viewing a bright light. Experiencing discomfort can distract drivers from the driving task, cause them to slow down, and cause drift slightly in their lane.
...
Vehicle headlamps are necessary for sufficient nighttime visibility and safety, and headlamp glare has long been recognized as a potential problem. However, concerns from the public about nighttime glare have increased in recent years. A public comment docket regarding headlamp glare opened in 2001 and has received more than 5700 comments to date, making it one of NHTSA’s most active dockets.
Several factors associated with recent vehicle and lighting developments may explain the driving public’s passion regarding nighttime glare. These include increasing light intensity levels, headlamp mounting height on larger vehicles, novel headlamp color appearance (specifically the bluish appearance of some headlamps), smaller headlamp size, variations in headlamp aim on the U.S. vehicle fleet, and an increase in the presence of auxiliary lighting, such as fog lamps. The increasing age of the driving public may be another factor. Since all of these factors have changed in parallel, assigning the cause of these concerns to any single factor is difficult.

Get stopped every week by folks that want the info on my lights, Police, Tow truck drivers, Security Officers, motorcycle riders. Some regular driver stopped and actually thank me for using the lights.
Tell your daughter that Professional Drivers are Taught, To Not look at Bright Lights.
Brighter is Better Here.

show us a peer reviewed article that shows that bright bicycle lights cause car crashes.
i have looked for such peer reviewed articles and found nothing.

There are laws and findings and reports and anecdotal evidence on the subject of bright vehicular lights. And a light that is too bright is probably just too bright whether what's behind the light is a driver or a cyclist.
