Stella Light System Operation
Normal Operation
The Light & Motion Stella LED lights all have one switch on the top of the head that controls power.
A brief button push activates “Cruise” mode where you will find 4 settings: High, Medium, Low, and
Flash. A single click cycles through each of these settings. Because our riders are versatile cyclists,
we design our lights to accommodate those needs. Stella Li-ion lights also have a “Race” mode you
can enter by pushing and holding the button to turn on. Race mode has only 2 settings: High and
Low, with a single click cycling between them. In either mode, pushing and holding the button for
1-2 seconds will turn off the light.
Note: The LED emitter and supporting circuitry used in Stella emit a weak electromagnetic field
and may interfere with some wireless cycle computers and hear rate monitors.
Aiming your light
Light & Motion creates lights with optics designed to reflect the maximum amount of light and
direct to where a rider needs it most. For best results at lower speeds, position your light so that
you get fill/peripheral light in front of the tire from the flood portion of the beam. For faster speeds,
you can position it slightly higher so that the spot portion of the beam shoots farther down the
road giving you enhanced depth perception and a long line of site. When aimed properly for high
speed, the road should be evenly lit in front of you.
With Stella Dual, you have both standard and flood headlights (spot is the one with the raised button,
and the flood is the one with the flat button). For best results, aim the standard light like you would
any Stella, and point the flood light head down closer to your tire so you have nice near-field and
peripheral light.
Battery Discharge Protection
All Light & Motion lights incorporate a battery discharge protection circuit. If the battery becomes
discharged, the light head will automatically dim down to preserve battery life, and eventually shut
off to protect the battery.
Low Battery:
Stella lets you know your battery is low in three ways:
1. a drop in light output,
2. a slow steady blink from the indicator light in the button,
3. a warning flash from the main LEDs.
Once in low battery mode, the indicator light will blink for the remainder of the ride, and the main
LEDs will flash every minute as a warning (for when your light is helmet mounted). You can easily
over-ride this main LED warning flash by simply pressing the button. We don’t want you to be
surprised by a low battery.
