Normal Operation
The Light & Motion Seca 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. Seca also
has 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 emitters and supporting circuitry used in Seca emit a weak electromag-
netic 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. Seca takes this one step further and introduces
our proprietary Gem-Beam footprint of light, which clips light from where you don’t need it
and redistributes it where you do.
For best results at lower speeds, position your light so that you get ample 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.
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 try and preserve battery
life, and eventually shut off to protect the battery.
Low Battery:
Seca 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 3 minutes as a warning (which can be seen when your light is
helmet mounted). You can easily over-ride this main LED warning flash by simply pressing
the button. All of these warning signals are to alert you so that when the battery is finally
dead and your light shuts off you are not surprised.
