IQ-275 Intelligent Lighting Controller (smart dimmer)

(Note: The IQ-275 replaces the IQ-175. It is easier to install and supports higher-power lamps.

For the new IQ-275 intelligent lamp dimmer (previously the IQ-175), this change greatly simplifies installation of the attached lamps as the lamp’s housing no longer needs to be electrically isolated from the chassis.

In addition, the power handling capability of the new controller has been increased. While the previous controller for P3 Lights, ST Lights and the Photon Blaster could provide 2.5 amps per side, the new controller can provide 6 amps per side. For the IQ-275 intelligent lamp dimmer the current rating has increased even more, from 6 amps to 12 amps per channel. When wired in parallel the new IQ-275 can source a full 24 amps, considerably higher than any current lamp dimmer available.

The IQ-275 Intelligent Lighting Controller from Skene Design allows you to quickly and conveniently set the brightness of your auxiliary LED or incandescent lights to match riding conditions.

Often auxiliary lights are too bright or have too wide a beam pattern to operate at full power during the day or under certain road conditions. With Skene Design's innovative intelligent lighting controller you can pre-program several different brightness settings and with the flick of a switch immediately select the desired brightness. There's no fumbling with a knob or a wireless remote trying to guess the best level.

Operation:

The IQ-275 has been designed by a motorcyclist for motorcyclists. It allows you to quickly and safely select just the right brightness level for you auxiliary lights without having to look at a knob to turn or read a screen: you simply flick a 2 or 3 position switch or double tap a button.
It has two possible modes of operation depending upon the type of lights you have, driving or fog lights. In Driving Light mode, when your motorcycle's high beam is off the controller will set the auxiliary lights to one of several user-programmed brightness settings depending upon the position of a brightness switch. When the motorcycle's high beam is activated, the controller overrides the switch setting and sends full power to the lamps. In Fog Light mode, the same brightness selection is used but when the high beam is activated the auxiliary lights are turned off.

Multiple brightness settings are available with the use of an optional, customer-provided switch. If a two-position toggle switch is used, two brightness settings may be selected in addition to the high beam override. If a three-position center-off toggle switch is used, three brightness settings may be selected. Each of these settings is adjustable from off to full brightness in 10% steps, providing very flexible and convenient control over the lamps' brightness. You can even use a momentary-contact pushbutton switch to toggle back and forth between two brightness levels. (The turn signal cancel switch on the right handlebar on BMW's can be used for this purpose.) If no switch is used, the lamps will come on at a single, programmable brightness level when the high beam is off.

See the wiring diagram below for details.



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 no dimmer switch is used and 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.

The table below shows the default brightness settings for each switch position.
Switch Position --
Yellow Wire Connection-- Default Brightness Level A Not Connected 10% B Ground 20% C +12 volts 50%

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


Note that each of the three positions may be programmed to any brightness setting, including off.
With this configuration, brightness settings for various riding conditions can be programmed into the
IQ-275 and instantly selected with the flick of the thumb, rather than having to look at and twist
a small knob as is required with other LED dimmers. Connect the IQ-275's white wire to the bike's
high beam wire to enable maximum brightness whenever the high beam is on.

When converting an off-road bike for road use, the above switch or any other 3-position, center-off switch,
programmed to OFF, LOW and HIGH brightness settings, can be used as a headlight switch . In such a
configuration the white wire would only be used only during the initial programming of the controller to set
the desired brightness levels. Programming is done 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.

Note that the button on this switch, as well as the high beam, may be used to program the IQ-275 and activate
the ALERT! feature on the IQ-275-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-275-A's white wire as shown below.
The diodes are 1N4001 or equivalent, (1 amp, >50 volts)



The controller has two identical channels, each of which can power a 144 watt/12 amp load. The two channels can be connected in parallel to power a combined load of 288 watts/24 amps. This is the recommended configuration if unequal loads are to be driven, as it will balance the loads over both channels.


The positive connection from the controller can be connected through a fuse directly to the vehicle's battery. No separate relay is required, as the controller performs this function. This simplifies wiring, eliminates extra components, and improves reliability compared to the traditional relay wiring harness.

ALERT! feature

A unique ALERT! feature is available on the IQ-275-A model. This allows you to rapidly modulate the brightness of the lamps attached to the controller when you really need to be noticed by traffic ahead.

When you need to maximize your visibility, just tap your high beam switch twice within one second, and the controller instantly responds with a brief, but highly conspicuous flashing sequence. No matter what brightness you have the lamps set to, even if they're off, they will immediately flash at maximum brightness in a very conspicuous sequence, like an over-caffeinated high-beam switch. The sequence takes less than two seconds, but will greatly improve your likelihood of being seen. Normal application of the high beam or a single tap will not trigger the ALERT! sequence, so it has no effect on your usual riding style.

Installation is quick and easy, and the controller can be used with almost any motorcycle.
A comprehensive installation guide and all necessary connectors are included.


Note 1: The 2014+ BMW R1200GS with LED headlight option provides no access to the high beam wire, so a separate switch is required to select high beam override and to program the unit. The model with incandescent headlights works normally.

Note 2: Some LEDs have 3 wires rather than 2, where the third wire is a dimmer input. These include :

  • Denali dual-intensity DX and D2 models
  • Cyclops Optimus
  • VisionX Optimus
These lights require a slightly different wiring method and shown in Fig 1 below.....

Note 3: While the great majority of aftermarket LED lights can be used with the IQ-275, a few are designed such that they will not operate properly with a dimmer. These include:
  • Rigid Industries D Series Lamps (D2 and Dually) and SR models. Models manufactured after 7/2013 are no longer able to support the IQ-275 or any other dimmer due to a design change. Other Rigid LEDs work with our controller.
  • KTM 990 Supermoto Auxiliary LED Light Kit, part number: 62014910033.
  • Denali D4: While early Denali D4 LED's were fully compatible with the IQ-175 & IQ-275, the current model of this lamp is no longer able to support the IQ-275 or any other dimmer due to a design change. Other Denali LEDs work with our controller.

IQ-275 Install on 2016 BMW R1200RT February 2, 2017
Reviewer: Phillip Hodge from Edmonton, AB Canada  
Item was easy to install after I got the correct size Posi-Tap, (1 supplied is too big for BMW Can-Bus wires 22awg).
Works as described.

REPLY FROM MCI: The Posi-taps included with the Skene Lights IQ-275 are intended for connection on typical headlight or heavier ground wires. They are too large for the thin 22 gauge CANbus wires.  The IQ-275 connects independently from the CANbus so there is no need to tap any of the CANbus wires. However, alternative Posi Tap sizes can be purchased from us as well
