Have you ever been perplexed about what sort of lighting to purchase for yo=
ur trike or bike? There are so many types, sizes, running voltage, running = current, effectiveness, mounting requirements, etc., to consider and I find=
the need to have a number of small batteries and having to check them deci= dedly annoying. In short, there is a requirement for a "better mousetrap".

I purchased a number of RGB WS2812 8-LED strips and a couple of 1m lengths=
WS2812 strips for testing. Although I had a couple of Arduino Uno boards, =
I also bought an Arduino Nano. I tried a downloaded Arduino sketch using th=
e FastLED library but I couldn't get the Nano to run it for some reason. I = loaded the same thing to a Uno that has run other sketches and it runs perf= ectly. The LEDs run off 5V which leads to one power source for all lights.

The exercise has proved completely successful and I have an 8-LED demo run= ning a wide variety of colours and displays from a USB battery bank at 90mA=
.

My plan is to use WS2812 LEDs for everything except headlight use - tail l= ight (low intensity), stop light (high intensity), turn indicators, body in= terior lighting and display lighting with whatever colour, intensity and pa= ttern takes my fancy. The 8-LED strips will be generally put them in a smal=
l Jiffy box, replacing the lid with a diffusing panel. I do have a couple o=
f plastic panels that can be used for this.

There are plenty of examples of using WS2812 LEDs on the Internet.

If you get experimenting, please post your results here.

I fiddled a bit with a sketch and very easily managed to change it to a fla= shing indicator display. Had to experiment with colour to get what was suit= able but it quickly fell into place. Only a small step to a two-light-level=
tail/stop lamp and a couple of logic things and it is sorted.

Easy!

Have now got a working Arduino LED light controller in demo mode with 3 LED=
bars attached. There is still a little code tidying required before I uplo=
ad the sketch and I can provide some assistance if you wish to customise an= ything.

Features:

1. Left and Right Turn Indicators. Can be easily modified for hazard flash=
ers with non-programmed external switch.
2. Tail/Brake Light. Flashes low intensity for tail light and is replaced = with solid high intensity with a programmed brake light switch detection.
3. Static white light for other uses such as reversing, interior (programm=
ed for flashing at the moment). Could be easily changed for front "running"=
lights with minor code changes.

If one is so inclined, one can easily add multi-colour, multi-pattern eye-= catching display lighting using one of the many Arduino sketches available = from the Internet. This is something I will add to my Warrior trike for the=
O'Keefe Challenge in April.

So, what is stopping you having your own unique bike/trike lighting?

Successfully tested basic operation of installed rear lighting today.
Have added a small "dashboard" with repeaters for rear lighting. Most reas= suring to see telltale dashboard indication that the lights are functioning=
as designed. Not much fun to find that the USB power plug has fallen out (= happened on earlier trials) and the tail and indicator lights that you thou= ght were being displayed, actually weren't there at all. A cursory glance a=
t the dashboard and one returns to a calmer state.
A word of advice. I detest those micro USB connectors at any time. Add the=
vibration on a bike or trike and there connections can become iffy at best=
. They need to be firmly fixed in place (insulation tape) and prevented fro=
m vibrating. Vibration is the worst enemy of any connector. Hard wired woul=
d be best.
The next stage is to add the fancy lights for the Light The Trail ride fro=
m Axedale to Heathcote on April 26th. This will be a separate Arduino for a=
quick fix but will be incorporated into the lighting controller at a later=
date. After that comes LED additions for the front and a dedicated 5V powe=
r source from the onboard 12V battery.

A successful LED lighting trial for during the O'Keefe Challenge April 26 a=
nd April 28.
The Light the Trail Night ride included rear lights powered by a USB batte=
ry pack that ran the flashing tail light, indicators and even hazard lights=
at one stage. This was for riding from Axedale to Heathcote and back - abo=
ut 66km. There was no diminishing of light output and no interruption to th=
e lights with the USM power cabled firmly tethered to the battery pack to p= revent it vibrating out. The battery pack indication was that it would have=
lasted 3 or 4 times that distance.
In addition to the rear lights, I ran a 3 metre long, 90-LED display light=
ing strip from one side, up towards the front and down the other side with =
20 or so different display patterns. This lit up both sides of the riding t= rail and is an indication of what white side lighting and reverse lighting = could do. Great. This was powered from my on-board 9AH 12V SLA battery via =
a simple 7805 (1.5A) regulator. I ran it all the way to Heathcote and back = without any problems.
The Challenge ride, 42km from Junortoun to Heathcote only required the rea=
r lighting. Altough not a great distance, it ran the taillight for the 7 ho= urs duration and indicators/hazard flashers for 3/4hr less than that. This = only depleted the battery pack by an indicated 25%,
I forgot to mention the dashboard indications were powered as well. Improvements? Front lights, change colurs of dashboard display to mimic re=
ar lights, a couple more 5V regulators to power all from 12V battery (might=
not suit you but you could use 18650s instead) and a power distribution pa= nel from the battery. I now have to do it properly.
All in all, a very successful trial once I discovered that the cyclicly in= termittent e-Assist USB outlet did not power the microprocessor reliably. Y= ippee!!
