Flashing rate and intensity adjustion


• Circumgyrate stopper end to OPEN, open the stopper end, you will see manual switch, intensity adjusting switch and light adjustment switch.

• Switch adjustment : open, toggle switch towards the ON side; off, toggle the manual switch toward the OFF side. (Note, Whenin the ON state, only at ≤ 300 lx ± 100lx illumination environment, the light will work.)

• Light adjustment : manual adjustment of the encoder SWA and SWB, each regulating group corresponds to one lighting mode.

corresponding 250 kinds of lights below annex, (6 lighting modes can be customized.)

Lighting Code



Steady burning


Flashing in fixed time, for example: FL (2) 5.5 S flashes twice every 5.5 seconds




Quick flashing


Bright and dark light, Lighting time longer than extinguish time.  


Equal light, Lighting time is equal to the extinguish time


Long time, long flash


Morse signals, including letters

 For example: VQ (6) + LFL 15 S.6 times within 15 seconds then long flashes once.

• Light intensity adjustment: Manually adjust the switch SW1 1,2- two code, different locations represent different light intensity. Details can be found in light intensity value on the left section of Fig.

Installation and Operation

•  Please read this manual before using this product.

•  Solar navigation light must be installed in a place where sunshine can be fully received, to ensure that the solar lights can work continuously.

•  Keep lamps and fixtures installed in the axis perpendicular to the mounting surface, mounting surface should be smooth and have sufficient mechanical strength.

•  If first time using, the light does not burning or weak burning in dark environment, put the solar light exposure to sunlight for 12hours, then it will be normal burning. ( When recharging the light,please keep the hand switch on.  If not,recharging is not available).

•  If stored for long periods, manual switch should be put OFF side, and in a low humidity and dry place, every 40 days set the solar lights out exposure under sunlight to ensure the battery capacity. (Please turn on the switch when putting the light in the sun)

•  The light is built in Ni-MH battery. After 450 (15 months) using, the battery capacity will decline to initial battery capacity about 80%, please change the batteries.

•  Manual switch is installed at the light bottom to protect the battery during transport and storage, and factory setting state: Switch—Off, FLASH CODE:F (Steady light) SWA:0,SWB:0, Intensity—100%  .Put it to ON-side before installation or test, then adjust flash and intensity

•  Any questions in operation please contact us.
