My iPad with its auto exposure doesn’t capture the brightness of these blinkies but they are all quite blinding — and inexpensive!

These are my favourite tail lights. These have built in solar chargers. You don't need to recharge them, or replace batteries.
At the time of writing, you can buy these on ebay for less than US$3.

Those are worth a try, but you may still want to replace the battery eventually. My solar marker lights on my driveway don't hold a charge for long anymore. I've been meaning to replace their batteries.

However, at less than $3 per light, it is probably easier to replace the light. If a light got broken or stolen at some time, replacing it should not cause financial stress for most people.

I love anything by KNOG. I've owned several. Seems that battery life is on par with other products out there (if not better), interface with bike is fantastic and features/settings are excellent.

I received my latest tail light today, about 3 dollars, no idea who the manufacturer was but was common on 1960s Romet bikes from Poland. I am not sure how bright it will be, but it will snuggle up close to its bottle dynamo.

I suggest an LED bulb for that tail light, @Geepig. If it casts its light in many directions, you'll get more light per watt.

The all-important left turn signal
"I'm taking the lane"
Bicycles usually go around parked cars, not slam into them.
This is the only way to get the message across, it seems...
Anyway, IIRC these lights cost about $1.67 each . The OP asked about the cost of the light,, not the cost of the battery, which is 12 volt. I recently converted from. Lead/acid to Lithium Iron Phosphate, but the cost of LiFePO4 has come down to where it is more economical than lead acid.

Some day I plan to make brackets to attach to my racks so I can fit multiple tail lights. A motorcycling friend once surmised that car drivers seem to recognize a triangle of lights much better than a single light, so that's what I'm aiming for. It would also give a better sense of the width of the bike so, hopefully, cars will give adequate space when passing.

This 🔝 is what I have my tail lights mounted on.



I’m working on a 15 inch cube next (So it will fit in a 16” cube cardboard box).
I want you to see the plan, so you can grasp the simplicity of it. It’s one box that does the work of three , left, right, & top.
Corrugated Polypropylene can be found at Home Depot, it’s right next to the plexiglass, near the shower doors.
LED lights can be found on Amazon.

I buy LED blinker modules by the 5-pack
This plan is better than making brackets.

Glues. I’ve used hot-melt glue, which bonds quickly, as soon as it cools. And I’ve used a construction adhesive called Loctite PL, which comes in a tube that fits in a caulk gun. It requires a lot of clamps. I had to use boards ,1”x4” , about 28” long, and sandwich the seams, with carpenter clamps outside, there was no way to fit the clamps otherwise.

Front and rear are cut from another piece of Coroplast (or similar corrugated polypropylene) keeping the grain horizontal.

The pattern for the sides, bottoms, and wheel arch. You could conceivably cut two of these from one 48” by 96” sheet, if you fudge it a little bit, I’m leaving two inches of flap to fold over and glue…

Pattern with locations marked Blue lines cut Red lines fold

Pattern with measurements marked in millimeters (And I spelled “height” wrong)
