This DialDim lighting controller has the same features and settings as the universal controller but includes a plug-and-play wiring adapter for effortless installation on the BMW R1250 GS and other motorcycles in the R1250 series. Simply connect it to your battery and a socket under your seat to unlock unique flash functions and independent dimming control of two sets of DENALI driving lights.

DialDim™ Lighting Controller

Provides a complete solution with easy control of all lighting functions.

Turn on/off and independently dim two sets of auxiliary lights from a single switch.
The LED halo switch displays your exact settings
Unlock smart flash functions that can cancel your auxiliary lights with your turn signal, flash your auxiliary lights like a turn signal, or flash your lights when you honk your horn.
On/Off & Dim
Independently control two sets of lights on/off and brightness level using the DialDim™ switch. The blue halo controls light set 1 and the green halo controls light set 2. Double-click to toggle between the two circuits.

High/Low Synchronization
Your auxiliary lights will automatically switch from your current setting to full intensity with your vehicle’s original high beam switch. Simply connect the blue input wire to your vehicle’s high beam circuit to activate this feature.

Stealth Mode
A smart 0% brightness setting on the switch allows your lights to be "off" during normal riding conditions but switch to 100% brightness with your vehicle’s high beam switch. In this mode, the lights also respond to turn signal and horn signals but remain off when not detected.

Turn Signal Cancellation
When activated, the main lights (blue circuit 1) turn off in sync with your original turn signal. Simply connect the yellow and orange input wires to your vehicle’s turn signal circuit to enable this function.

Flash as Turn Signal
When this function is enabled, your lights (green circuit 2) will flash in sync with your original turn signals. Simply connect the yellow and orange input wires to your vehicle’s turn signal circuit to activate this feature.

Horn Strobe
When enabled, the auxiliary lights on both circuits flash at 4 Hz when you honk your horn. Simply connect the green input wire to your vehicle’s horn circuit to activate this function.

Electronic Fuse Circuits
Both lighting circuits have electronic fuses and can be reset directly from the switch itself! The halo lights up red to warn you of a circuit fuse trip.

Voltage Indicator
When the vehicle starts, the switch halo flashes green to indicate a healthy battery voltage or red to indicate battery voltage below 11.8 volts.

Low Voltage Cutoff
If battery voltage drops below 10.8 V, the lights will not turn on, preventing you from being stranded. The switch halo flashes 4 red LEDs to indicate the low voltage condition.
