We always recommend bringing your light with you in your carry-on luggage. Different security agencies have been known to disassemble our lights and there is no guarantee they will be re-assembled correctly. This of course would be unnecessary since our lights are considered a factory sealed, battery integrated product. But it never ceases to amaze us when a TSA officer feels so inclined to pull apart our lights.
To keep your lights from discharging and possibly cooking your undergarments, use both the Travel Lock-out Mode feature as well as the Slider Switch Lock-out. This ensures safe travels and prevents any frustration come the first dive of the day.
It's also not a bad idea to get in the habit of locking your lights after your dives before the car ride home.
Travel Lock-out Mode
Most Light & Motion lights are equipped with a travel feature that will prevent the light from inadvertently turning on should the power button or switch be engaged while the light is in your pocket or backpack/suitcase. This feature is called Travel Lock-out Mode and is standard on all Sola models (except Photo), including the Tech 600 and the Nightsea.
These will have a Lock icon on the slider switch. While the light is off, hold the switch forward for 5-8 seconds until the dashboard LEDs begin flashing red. Trying to turn the light on after this will result in the lights flashing red but the light not turning on. Repeat this procedure until the lights begin flashing green to unlock the light.
Slider Switch Lock-out
All Solas have a rotating slider switch that prevents the slider from moving. Simply turn the switch dial 90 degrees so that the ridge on the switch points towards the front and rear of the light.
