Dinotte tail light - how wide is effective viewing angle?

I know the Dinotte is supposed to be a very bright tail light but I have not been able to find any info on how wide the effective viewing angle is. Can anyone tell me how wide the effective viewing angle is?

I've been trying to find this out for months. No one seems to have any decent information or photos. I'd REALLY like to see a daylight photo from behind, at a distance, with the stock seatpost mount.

They don't have any photos of the taillight in action. What I'd really like to see are some real world shots.

I bought one a month ago and the brightness is amazing. Utterly blinding from direct angles. At 45 degrees, it looks like the common led blinker. On a direct line, it hurts.

Three levels of constant light (low, med. hi) and one blinker mode.

Is it very visible during the daylight using the stock seatpost mount?

From directly behind, yes, it is very visible during daylight.

If the light is that bright, but in a narrow cone, I'd sacrifice some of that "beam" and mount a diffusing lens of some kind, to give it a bright but wide light, much like rear lights on cars.

I accept the reality that the Dinotte is is blinding when viewed straight on. So are some normal LED tail lights I have. However, if you are off center by much, they lose most of their punch. In the daytime, they need to hit you almost directly in the eyes to be of much value.
If I am going to pay big bucks for a Dinotte tail light, I need to know that it provides a wide viewing angle in the daytime.

Still looking for some solid info. Picture in daylight from different angles would be great.

I agree completely. I wonder how the light being pointed at the ground effects it's visibility in the daytime? Many owners of this light say how wonderful it is but none are willing to take a few daylight shots. Why?

I guess because they didn't buy it for the daytime and don't have the time to satisfy your request.

Based on my observations, the Dinotte is the brightest bike specific product that I have seen on the market. If you want something designed specifically for daylight visibility, you probably need to look at other sources.

I can say from personal experience that if you are riding at night with someone who has one you will ask them to ride in the back or put it on low and point it downward.

Cause you need to:

1) Be part of the club
B) Say "Pretty please"

Cool! Thanks a lot!

Is that with the stock seatpost bracket which is angled downward, or did you modify it?

Stock seat post mount. This position tends to rub my thigh though so I usually have it on an alternative mount directly under the seat.

In hindsight, it may have just a hair more down angle, the bike is parked in my rack which elevates the frot wheel about an inch or so.

+1.
Thanks for the daylight shots. That is what I have been looking for. Your photos suggest that it has a decent view from off center and that is what I was looking for. I use my taillight anytime I ride. I will take all the visibility I can get...day or night.
