Some motorists seem to not see me when they are on-ramping traffic circles.
Please recommend a safety light that I can have on my right arm, or side of bike that will help them to see me.

10 Wheels

Put one of these on your helmet.

I agree with 10 Wheels. Put a light on your helmet so you can shine it in their faces. Make sure it is plenty bright; a dim light would create the illusion that you are further away than you are.

I use spoke lights. They do eat up 2025 batteries though.

I've seen a couple of guys with this set up. Takes forever for a motorist to figure out what it is. Some kind of amber/red sidelights would be much better IMO.

10 Wheels

You can aim it right at their face. I use mine on strobe.
I am Not able to make any car Stop, but I can confuse them.

Good reflectors can help quite a bit. They can help provide size and distance information that a single tiny bright light doesn't. Broad reflective stripes on garments, spoke reflectors, strips of truck conspicuity reflective tape, etc...

You probably do not want a blue light. Something white would be better.

10 Wheels

The Blue is Best. Adds to the other colors.

Not legal in MA to run blue lights. Those are reserved for the police.

I ride to Be Safe, Not to Be Legal.

I have some blue Bike Brightz...never been stopped. My wife once thought the police had a car pulled over as she drove home but it was just me. The only issue I have is short battery life in the cold but they can be easily mounted to a fork or chainstay. https://bikebrightz.com/

I too ride to be safe, I like yellow, amber, white and red for my lights.

The Axiom Pulse 60 LED USB Re-Chargeable Taillight. It has three settings of 'steady bright'. Along with one fast strobe and one slow strobe setting. I was a Planet Bike devotee. Until I was rear-ended in broad daylight. It is brighter than most automotive taillights.

That is why(so I can shine it in their faces), I got the Axiom Pulse 60 taillight. It is brighter than everything else I have tried, and it is a rechargeable LED, instead of wasteful alkaline.

I find blue LEDs very hard to focus on in the dark, so I stick with reds and whites.

Some tires have retro reflective sidewalls. They are very effective when illuminated by headlights. For the most part, if you care about a driver seeing you from the side, it is because he is going to t-bone you. Meaning, his headlights are on you.

It's illegal to shine a white light into a drivers face. Also, no reason to temporarily blind them when they are coming in your direction. Not cool.

Chris516

Illegal, yes. But in a way, how will traffic see a cyclist when they are already 'blind as a bat', regardless of a cyclist having a bright white light. Also, If it is illegal for cyclists' to do that, the same thing should apply to motorists'.

2manybikes

The law applies to everyone. If they don't hey don't look, or don't notice, a side light of some kind may help, it is a problem. But temporarily, even for one second blinding them or reducing vision is no help. Drivers don't notice cars or trucks sometimes, not just a cyclist. It's a problem.
If they are coming right at you reflective tape and plastic reflectors work great. Reflective tape on the moving wheels is very noticeable. Also the tires with reflective sidewalls are great. Experiment with different things at home. This could allow you sit in the car and look at your bike from the correct distance and position, if you have room. Google images of bikes from the side, or wording similar.
The white reflectors on bike spokes, that everyone takes off are very effective. The motion is eye catching, and it may signal "bicycle" to some drivers. I test all my lights and reflectors, it's a big help.

It is the cars coming at an oblique angle, on the oncoming ramp, into the traffic circles I ride in. The ramps approach the circle at a diagonal, facing away from oncoming circle traffic.
Their lights aren't on me.

But, I have been wearing a helmet light and a quick, friendly, passing shine into their cabin seems to be doing the trick. They seem to be slowing now after I give the friendly light pass.

B. Carfree

Prove it, please. I don't recall a specific item on this in the vehicle codes of any state regarding what is legal in terms of bicycle lighting. I'm sure Germany has addressed this, but I'd love to see what you have here in the states.

By the way, I'm not talking about a two thousand lumen photon torpedo, just enough so that I can see the face of the driver and can determine that s/he has seen me. Shining a helmet light into the face of motorists who are in the process of rolling stop signs has saved me many a broken bone while I ride at/near the 30 mph speed limit on urban streets with parked cars. In those situations, the lights on the bike are often too low to be seen over the parked cars, so the helmet light is the only chance they have to see me.
