You're kidding, right?

I have a 140L and run it flashing (the single flash over low mode) day and night. I've received nothing but praise from motorists. They like it, universally, and give me plenty of room.

I hardly think a Dinotte light is even comparable to the headlights from other cars drivers see all the time.

^^^also people tend to be smart enough to not stare at a bright light, uh, like the sun for instance!

When I look out of my windshield and see the sun driving down the road in front of me, I'll keep that in mind. :-)

If you're thinking of a bike light, I certainly hope drivers won't stop looking down the road in front of them so that they aren't staring into the bright light.

Listen Paul, you're from Minnesota which makes you all right in my book! We all want to be safe out there and I think the folks at Dinotte are helping us out a lot. I'm glad I have the 140L as an option as most of us are. For those that don't have one, the issue is typically affordability not performance, they work great but you already know that.

The whole "car headlight" thing is largely untrue -
1. Car headlights are required by law to have a shaped beam that puts out very little light above the horizontal level of the light. The amount of light you get hit with at driver level is much smaller than the amount of light you would see if you put your head down at the level of the light.
2. Even at it's closest, an oncoming car is several feet to the side of another car. If you take the lane and have a rear light (unlike a front light), it's pointing directly at the person driving the car.
3. What's hard on your eyeball isn't simply a matter of lumens put out, it's also a matter of the size of the light source. Car headlights are rather large and spread their light out from a larger object. The Dinotte is very small and it's all coming from one place.

I say the last one from experience. Last fall I rode home with a Dinotte 200L front light on a bike path along a river that's right next to a road. Car headlights were a mild annoyance, nothing more. What was really blinding was the several bikes I passed with these really tiny, bright lights. I even saw a pair that were mounted all the way down on the quick release - they were actually the worst. I was really surprised, I thought mounting it lower would be better - go figure, I imagine they were the physically smallest lights and thus the problem.

Usually front lights aren't as big of a deal because you aren't pointing them directly at people.
