The 1400 lumen bike light is as bright as a car light so I can see where I'm going, rather than my other light which lets people see me.
Putting my ear close to all the connections in the cables, it seemed to me that the connection where the three cables (switch, power source, light) join up was flakey. Inside the plastic mold where the cables join up is a circuit board.
So I had to get the
circuit board out. There was no easy way to access the circuit board as the
plastic had been moulded on. This meant cutting away the plastic with a blade –
very carefully. I was lucky that when I cut it open, I started on the side of
the circuit board that didn’t have all the important
things.
With the plastic out
of the way, I cut off the switch cable and cut away the switch cable wires from
the circuit board.
Next came the tough
part. I had to re-solder the wires to the switch board (I could have left the
wires on and just fixed up the connection – but it seemed less fiddly if I
started from scratch.
So I made the 10km
bike ride over the mountain. I bought a
soldering iron, solder and a fine tip for the iron.
I soldered on the
wires (having previously taken note of the correct order of colours - from the power source, red, white, green, black). Then I had
to check if it all worked. I plugged the power source in and it all worked!
without any flickering!
The connection needs
to be water proof, so I taped it up and then put candle wax on it, using a
candle and a milo lid as a pan. The wax was too crumbly, and was a
failure.
Then I tried hot glue
gun, which worked perfectly.
