IQ-175 Intelligent Lighting Controller (smart dimmer)

IQ-175, IQ-175-A Wiring



(Note: Some auxiliary lamps have the negative lead internally connected to the lamp's housing. This type of lamp must be mounted such that the housing is electrically isolated from the vehicle's chassis.) 

In driving lamp mode, activating the high beam switch sends full power to the lamps. 
In fog lamp mode, activating the high beam switch turns the lamps off. 

If the yellow wire is left disconnected, the controller can be programmed to operate the lamps at any brightness from off to 100% when the high beam is off. If more brightness levels are required, a two or three position toggle switch or a momentary-contact pushbutton switch may be connected to the yellow wire as shown in the following diagrams.


Optional Two Position Switch Optional Three Position Switch Optional Momentary-Contact Pushbutton Switch
This allows two independent brightness 
settings, A and B to be selected,
This allows three independent brightness 
settings A, B and C to be selected, 
A double-tap on the button will toggle 
between brightness levels A and B. 
Note: BMW turn signal cancel button on 
right handlebar may be used for this purpose


Any 3-position switch as shown in figure 4 may be used to switch brightness levels. 
One example is the Trail Tech handlebar switch. Wiring for this switch is illustrated below.


Switch Position Yellow Wire Connection Default Brightness Level
1 Not Connected 10%
2 Ground 20%
3 +12 volts 50%


Note that each of the three positions may be programmed to any brightness setting, including off. This allows the above switch or any other 3-position, center-off switch to be used as a headlight switch, with OFF, LOW and HIGH settings. In such a configuration the white wire would only be used during the initial programming of the controller to set the desired brightness levels. Programming is done once upon power up by touching the white wire to +12 volts, as described in the programming section of the manual. The white wire is then insulated and tucked out of the way.

The button on this switch may be used to program the IQ-175 and activate the ALERT! feature on the IQ-175-A. The wiring for this is illustrated below. The diodes are 1N4001 or equivalent, (1 amp, >50 volts).



The horn can also be used as an ALERT trigger, by connecting the hot lead on the horn to the IQ-175-A's white wire as shown below. The diodes are 1N4001 or equivalent, (1 amp, >50 volts).

If a two-position toggle switch is connected to the yellow wire as shown in Figure 3, setting A or B may be selected. If a three position, center-off toggle switch is used as shown in Figure 4, setting A, B or C may be selected. If a momentary-contact normally-open pushbutton switch is connected as shown in figure 5, then a double-tap on this switch will toggle between settings A and B. If no switch is used, the bare end of the yellow wire should be insulated with tape or the included Posi-lock connector. The lamps will then illuminate at setting B. 

Programming Different Brightness Levels


Programming different brightness levels into the IQ-175 is very easy. Skene Design has developed an innovative method that uses only the vehicle's high beam switch. 
The brightness of each setting may be changed from the default value in order to suit your own requirements. This is done as follows: 

Ensure that the high beam is off, then turn on the ignition. The lamps connected to the controller will come on at low power for three seconds. This is done to minimize power drain on the vehicle’s battery before the engine starts. The lamps will then flash briefly two times and go to the brightness level determined by the connection of the yellow wire. 

To program different brightness levels, as soon as you see the two flashes from the lamps, immediately flash the high beam three times before three seconds have elapsed. The controller will respond by flashing the lamps back, signalling that the unit is now in programming mode. 

Once in programming mode, each time the high beam is switched on then off, the brightness for the setting selected by the brightness control switch will increase by 10%, up to 100%. The next increment beyond 100% will cycle it back to 0% (off). 

When the desired brightness for this switch setting has been reached, move the switch to the next position (or hold down the push button switch if that is being used) and program this setting in the same manner. 

To exit programming mode, turn the ignition off. Programming mode will also end if no activity is seen on the high beam switch for 20 seconds. 

The new brightness level for each setting is saved in non-volatile memory and will be remembered the next time the ignition is turned on. 


HEX ezCAN Accessory Manager

The HEX ezCAN accessory manager is designed for the liquid cooled BMW R1200GS, R1200GS Adventure, R1200RS, R1200R and R1200RT. This device is ready to power left and right auxiliary lights on an individual, high power, 10 amp circuit as well as an auxiliary brake light and accessory power on separate, low power, 4 amp output. The ezCAN plugs into the motorcycle CAN-Bus with the factory type connectors. As the unit listens directly to the factory CAN-Bus system, there is no need to install extra switches for your auxiliary lights or horn as the ezCAN interprets commands from your motorcycle’s existing controls, including the Rotary Multi-Controller ("Wunder wheel") adjacent to the left switch cluster.
