Connecting the Police Motorcycle dual flasher w/headlight (modern-era)
The N8082 is designed to alternately light 2 series-pairs of LEDs, (1 red & 1 blue in each pair) to simulate the emergency strobe lights on the front & rear of a police motorcycle. Solder points 3,4 & 5 drive these LEDs. An additional output is provided for a white LED for a headlight at points 6 & 7.
Installing
the N8082 is very
straightforward. Because the module has circuitry on both sides, care must be
taken to be sure that the components or wires soldered will not make contact
with any metal object which could cause a short
circuit.
Included with
the module are two 6” lengths of #32 insulated wire. If necessary, these can be
used for power input wires. If used, we recommend the red wire be used for the + DC connection. It would be connected to solder
point
1 as shown in Fig. 1. This wire
could also connect through a switch to the + DC connection for remote control of
the lighting effect. The other (black) wire should be connected to – DC and to
solder point
2.

Important note: A low-wattage iron with a pointed tip should be used for connection of wires. Too much heat or solder can easily damage the wires, decoder or module and void the warranty.
Also, all connecting wires should be pre-tinned before soldering them to the module. This will make connection quick and easy and ensure excessive heat is not applied to the solder points.
Connecting LEDs
When
connecting the LEDs, proper polarity must be observed. LEDs are “polarity
sensitive” and will not function if connected backwards.
The N8081
is configured for the connection of
2 series pairs of
20 ma LEDs
(1 red & 1 blue in each pair)
to solder points
3,
4
&
5.
The N8081
has on-board current limiting resistance to protect these LEDs so no external
resistor is required.
Using wire appropriate for the size of the LEDs and their placement in your project, connect the LED anodes (A) and cathodes (C) together as shown in Figure 2 below. Note that LEDs 1 & 2 are a series pair (wired anode to cathode) and LEDs 3 & 4 are a second series pair. Anodes of LEDs 2 & 4 are connected in common to solder point 4. Additionally, a 5th LED (white type) is connected between points 6 & 7 with a 1K-ohm resistor in series as shown below. This resistor is included with the package (plus a spare)

This
completes hookup of our N8082
module. We hope the aded realism it provides enhances your enjoyment of the
hobby.
