The IQ-275 high-power programmable dimmer allows instant control of the brightness of auxiliary lamps with the flip of your factory High Low switch, No other switches need to be added.

The IQ-275 ties into the vehicles high beam switch to provide instant control over the brightness of attached driving or fog lights.

Note: If you have a bike with a factory LED headlight we advise you to get the IQ-275X witch has provisions for inverted headlight signal that comes on some of the bikes with factory LED headlights AKA. T700, 1290 Adv

Additional wiring and programming information is available in the IQ-275 area of our support page.

The IQ-275 has been designed by a motorcyclist for motorcyclists.

The controller also works great on UTv's and automotive applications. It allows you to quickly and safely select just the right brightness level for your auxiliary lights without having to look at a knob to turn or read a screen: you simply flick the factory low beam and your auxiliary lights will follow suit.

 Low beam is adjustable from off to 100% in 10% increments.

This powerful 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.

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.

There are two possible modes of operation depending upon the type of lights that you have.

  • 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
  • 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.

  • two-position toggle switch provides two brightness settings in addition to the high beam override
  • three-position center-off toggle switch provides three brightness settings may be selected in addition to the high beam override

Each of these settings can be programmed at any level 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.  If no switch is used, the lamps will come on at a single, programmable brightness level when the high beam is off.

ALERT! feature

The unique ALERT! feature available on the IQ-275-A model. enables you to initiate a brief, highly conspicuous flashing sequence when you really need to be noticed by traffic ahead.

Just tap your high beam switch twice within one second, and the controller rapidly modulates the brightness of the lamps attached to the controller. 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. 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.

Note 1: The 2014 and later model year 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. There is a slightly different wiring method for 3-wire LED models. Some examples include :

  • Denali dual-intensity DX and D2 models
  • Cyclops Optimus
  • VisionX 

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
