This DialDim BMW R 1300 GS / GSA Adventure lighting controller has the same features and settings as the universal controller, but includes a plug-&-play wiring adapter for effortless installation. Simply connect it to your battery and to a connector under your seat to unlock unique flash functions and independent dimming control of two sets of DENALI auxiliary lights.

DialDim™ lighting controller

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

Turn two sets of auxiliary lights on/off and dim them independently from a single switch.
The LED halo switch displays your exact settings
Unlock intelligent flash functions that can override your auxiliary lights with your turn signal, make your auxiliary lights flash like a turn signal, or make your lights flash when you activate your horn. 
On/Off & Dim
Independently control two sets of lights on/off and intensity levels using the DialDim™ switch. The blue halo controls light set 1, and the green halo controls light set 2. Double-click to switch between the two circuits.
 
High/low synchronization
Your auxiliary lights will automatically switch from your current setting to full intensity with the original high-beam switch. Simply connect the blue input wire to your vehicle's high-beam circuit to activate this function.
 
Stealth mode
An intelligent 0% light-intensity setting on the switch allows your lights to be "off" under normal riding conditions, but they will switch to 100% intensity with your vehicle's high-beam switch. In this mode, the lights also respond to turn signals and the horn, but remain off when no signal is detected.
 
Turn-signal override
When enabled, the main lights (blue circuit 1) turn off in synchronization with your original turn signal. Simply connect the yellow and orange input wires to your vehicle's turn-signal circuit to activate this function.
 
Flash like a turn signal
When this function is enabled, your lights (green circuit 2) will flash in synchronization with your original turn signals. Simply connect the yellow and orange input wires to your vehicle's turn-signal circuit to activate this function.
 
Horn strobe
When this function is enabled, the auxiliary lights on both circuits flash at 4 Hz when you activate your horn. Simply connect the green input wire to your vehicle's horn circuit to activate this function.
 
Electronic fuse circuits
Both lighting circuits are electronically fused and can be adjusted directly from the switch itself! The halo lights up red to warn you when a circuit fuse has tripped.
 
Voltage indicator
When the vehicle starts, the switch halo flashes green to indicate a healthy battery voltage, or red to indicate a battery voltage below 11.8 volts.
 
Low-voltage cutoff
If the 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.
