Happy to! (The water analogy doesn't always work! Water doesn't require a
circular circuit to flow.)
Parallel circuits:
Think of a 100 ft garden hose allowing a certain flow of water, depending
on hose size (resistance) and pressure (voltage).
Now think of two 100 ft garden hoses laying side by side = Two
opportunities for water/current flow = 1/2 the resistance = twice as much
water flow.
Series circuits:
Think of a 100 ft garden hose allowing a certain flow of water, depending
on hose size (resistance) and pressure (voltage). .
Now think of two 100 ft garden hoses fastened end to end, 200 ft total
length. Much reduced flow and pressure at the end of the hose. (Not
necessarily 1/2. .
Ohm's law doesn't apply directly to water. Cut a wire and the circuit is
"open" (not complete) and no electricity flows. Cut a hose and water flows all
over 'da place!
Next question??? ;~)

Thanks Gene. That was a good analogy.
Now, explain how two equal resistors wired in parallel cuts the ohms in 1/2
with a water analogy!
And why series = added together.

LED bulbs do not need a voltage/current limiting device. They are
long-life because of their tolerance for voltage variances - they do not
overheat and self destruct. They have a wide operating range - I have seen many
that are rated at 9 to 14.5 volts. Because of their reduced current draw
many turn signal blinker relays will not operate with them as the relays
require a certain level of current or energy flow.
Some pretty basic electrical terms, grossly simplified: (only for those
that admit they need them. Those that don't need not reply! :~)
When thinking about electricity, think of water. Voltage is equivalent to
(water) pressure. More voltage/pressure will push more electricity/water
through the same wire/hose. Current/amperage is the amount of movement
(electrons/gallons per minute) pushed through the circuit/hose. Reducing the
size of the hose or increasing the resistance of the electrical circuit will
reduce the flow of current/amps using the same voltage/pressure.
An electrical circuit is "circular" in nature, and requires a path from the
source (battery/generator/electrical outlet) through controlling
devices(switches/relays) through the operating device (starter
motor/lights/horn) and back to the source. On motorcycles/trucks/autos the
metal parts of the engine/frame are often used as the return or "ground" part
of the circuit. Where this path is uncertain, "ground" wires are used.
A "short" is when something occurs in the electrical circuit that allows
the current to flow through a shorter path than intended. Perhaps a bare wire
or terminal touching when not intended.
A "ground" is when the electrical circuit is allowed to "touch" or complete
a circuit before going through the operating device (starter motor/lights/horn)
which acts as current limiting devices. With the current no longer limited,
large amounts of electricity flows with often visually spectacular and
destructive displays! (And results!)
An "open" is where there is a break in the circuit, and the circular path
cannot be completed.
An "open" is never a "short", an "open" is never a "ground", and a "short"
is never a "ground" (unless it is "shorted" to ground"!)
Confusing enough? Any questions, class???

not sure about all this led stuff but from my reading if you don't
use a relay to reduce the juice the led will be short lived. can anyone add to
this? I want to go all led myself so I have more to use for other things and
as we all know the power on the Nighthawks is minimal...

My flasher went bad so I ordered a enlectronic flasher for $20 and it
worked with no mods. Just thought I'd pass along the
info:.............
