OK you have gone out and bought
those LED indicators cos nobody
had the sense to buy them for you
at Christmas, even though you left
brochures all over the place. You
wire them in, invite all your buddies
over to watch the unveiling, like
they would be as impressive as
New Year’s Eve fireworks on Sydney
Harbour and they start flashing like
an epileptic pig is switching them
on and off – Damn!
The “fix” is simple and very
cheap to do. You can buy a “flasher
fixer” package or for around $1 to
$2 plus a little bit of time.

RB LEFT: If you have gone to
LEDs front and back, you
can do each indicator as
above or just do them in
one place.
NOTE: The exposed wire
of red (positive) cable
needs to be insulated, so
wrap some insulating tape
around to cover just those
exposed wires.
ABOVE LEFT AND RIGHT: Connecting in the resistor, using a terminal or soldering.
ABOVE: Cut the two wires going to the indicator and strip them back.
