Would more lights on bike enhance safety?

I don't know of any studies of this, but I find that if the two flashing lights are facing me, the interference of the two blinking patterns with each other can be blinding and disorienting, especially if they're both bright white. It plays havoc with your pupils, that's for sure..
I actually like two tail lights out of synch on the back in very high-traffic, highly dynamic areas--(lots of lane-switching, driveways, side streets, where cars can be going almost randomly along the road---think of stretches of roadways between multiple major shopping centers at Christmas ..... )..... and Not two strobes, because I really don't want to be causing epileptic fits.

Even cars are getting crazy with the vast array of lighting on the rear and front.
Here in the USA, NHTSA for a long time remains too quiet and complacent about dealing with this. Maybe it's time to wake them up with some emails and letters.

As I read about close calls with cars on this forum and had 3 friends in serious accidents in the past 15 months, I am starting to worry more about safety and getting a little paranoid
I use bright colors and flashing lights in front and back but was wondering if there is any benefit (or any studies) to having 2 red flashing lights in the back.
One under the seat and maybe another in the lower part of the seat stay on the road side. Does anybody do this?
Seems to me that if I am driving and see one light I think bike......but if I see 2 flashing lights, I would be wondering what the heck is that.....and pay more attention.
Probably makes no difference if the driver of the car is on the phone texting............ Just looking for ways to improve my chances!

Just speaking for myself, I find lots of bike lights irritating. Cars don't need retina-frying brightness or hyperactive blinking modes to be seen, so I don't buy that we need it either. Healthy brightness, a good beam battern, and proper mounting will do about as much as is necessary to show that you're there.
If you're still convinced that you need a blinking light, it's good to pair it with a solid light to make your location absolutely clear. My old Axiom Flashpoint taillight had a great mode where one LED was solidly on and another two blinked. Since Axiom seems to have gotten out of making bike lights, I don't know who offers something like that now.

Yeah .... well, as far as I know it is illegal and unwise to aim a white light back .... the reason being that red lights are supposed to indicate the rear of the vehicle.
I actually like two tail lights out of synch on the back in very high-traffic, highly dynamic areas--(lots of lane-switching, driveways, side streets, where cars can be going almost randomly along the road---think of stretches of roadways between multiple major shopping centers at Christmas ..... )..... and Not two strobes, because I really don't want to be causing epileptic fits.

TBH, I forgot OP was asking about red lights. Two blinking, not strobing reds may be ok, but I'm not surer one blinking, one solid might not be better. Probably no way of definitively answering that, but either sounds pretty good to me.

In addition to a front facing headlamp (steady light) and rear facing taillight (low beam with bright blink interruptions), I also run a rear facing red steady lower down the seat tube, and another white light attached to the stem and pointing downward. The second red light is aimed at the front of the rear fender and cannot be seen from behind the bike. The other white light is aimed at the top of the front fender and also illuminates the ground slightly on both sides of my front wheel.
The purpose of these additional lights is to improve the chances of being seen from the side, as most of my close calls happen to be from drivers pulling out from side streets and parking lots. The lights seem to help quite a bit, and with the bike frame itself being illuminated from the reflections, I think other road users can more easily identify me as a bicycle and not just some random blinking lights.

One of my lights has a steady-with-flash option .... I agree one solid one flashing is probably optimal ... but as a rule I only run one light unless I am in really crazy city traffic, which I don't do much any more.

One steady white out front for seeing, another white strobe pointed down at the ground. This creates a pool of light on the pavement that is noticeable but not blinding.
on the rear I have one steady red on the rack and a smaller blinky on the left handlebar end. That way a car gives enough room to pass and not clip me.
Commuting I have one red blinker on the rear and one white strobe facing forward, but slightly downward, so as to be seen but not blind oncoming traffic.
As a driver, as well as a cyclist, I don't have to guess at what works. I just take note of what works for others. A forward pointed strobe, aimed low never bothers me. I am also never tempted to drive into the back of a red blinking bike. That is probably a sign of distraction and not hypnosis.

If it makes the driver behind you think that they're about to witness a cyclist getting beamed up to a UFO, it just might encourage them to give you some space.

Cycling in Oregon at night I was crashed into by a running teenager in a very well lit street and I had a very bright headlamp on. I was also dressed in dark colors. Blinding drivers with lights displays the wrong attitude for shared space. Sure put on bight lights no excuse not too but emulate other vehicles on the road not emergency strobe beacons like a sinking ship or helicopter running lights.

The most important safety feature is your brain and situational awareness. However...
I ride with one very bright light in random blinker mode in the rear and a really bright light in blinker mode on the front. I also wear hot yellow jersey or vest and hot yellow socks with reflective strips on the back. I don't ride in the dark or in heavy traffic.
However, my two most important safety features are my situational awareness and my Take-a-Look rear-view mirror. I am anal when it comes to what's going on around me, front, rear and sides. I DO NOT depend on "things" to keep me safe. I depend on ME keeping me safe. My head is always on a swivel looking for potential threats, always.
In the last month I have avoided two collisions with cars because I anticipated what the driver was going to do and braked accordingly. It doesn't happen often but it does happen.
Look for it, anticipate it and react accordingly without hesitation. Do not lose focus and go into yahyah land when riding.

Absolutely use lights, day or night.

I ride motos too and the high beam is on during the day. Yes, it works.

As a driver, I find that flashing lights can cause more trouble than they help if they're not done right. Rear red gets to be a problem if you have lights flashing at a high rate--it interferes with the ability to determine where you are and where you're going, especially if it's coupled with another flashing light.
One solid red and a relatively slow blink rate on another seems to work pretty well. Fast strobing makes no sense to me whatsoever either on front or back. I don't believe it really is significantly more effective at
drawing attention, and it just adds an element of confusion. Confused drivers make big mistakes.

You should ride drunk more often .... on the wrong side of the road, at night. Let's see how much "situational awareness" you really have. (Please get a few GoPros first.)
