Matters needing attention:

1， before you install the check the product， without any problems before installation.

2， this product is through the light control and vibration sensor， selfshining in the dark and vibration environment， is automatically extinguished in the light (or in the quiescent state after two minutes willself extinguish).

Check the product please put in the dark and vibration see whether flicker， if not flicker may be chip protection. The tail on the sun or light as atest again.

The main function of product:

1， reduce the drag coefficient， anti-static function

Automobile shark fin also called car roof wing， the product design conceptis a natural fish (including shark fin imitation)， because the fish fin effect，can reduce water resistance， but also can pose adjustment swimmingconvenient. The product is installed in the roof of the shark fin is the fishfin function by combining modern aerodynamics and design.

When the automobile movement speed in the air， will pull a long vortex.When the vortex in the rear of the car out， will produce pressure drag，while adding a spoiler at an appropriate position， can force the air moved，from laminar to turbulent flow， reduce the frictional resistance andpressure resistance， thereby reducing the coefficient of drag， but also can release the static electricity， effectively reduce the body attachment dust，dirt， reducing the noise， but also can provide certain pressure to stabilize the body!

2， rear end collision prevention function

In the evening， our car taillights are often bright red light， for fatigue drivingor driving for a long time after the car drivers， have a habit of numbnesson the color， does not cause their attention; or because of the oppositeautomobile light irradiation， and this is not easy to find us in front of the vehicle it is very easy cause， rear end accidents. So， we added the LED lights flashing in automotive shark fin.

Because people are more sensitive to the flashing lights， so the product can be in the running time is to remind the warning role， so that after the car driver is found early， in order to prevent rear end collision preventingeffect!

Switch， light color， flashing mode control: the product is provided with a switch function keys， press the function key for 2 seconds can be open or closed warning light， open after the click a conversion to a flashing modeor light color， light color is blue， red， green， blue， red and green， Lan Honggreen， 7 color options every kind of light color， there are 10-20 flashingmode.

This combination， three water-proof design: the product is provided with the vacuum layer， the water， glue layer three water-proof function， impact force， first step decompression layer reduces wash water cannon， the second step， the water will be after decompression water from thebottom guide on the other side of outflow. The third step， the product is equipped with large glue， can seal the product bottom cover and the main body joints， prevent the rain water and after decompression of thewashing water into the warning light inside， and products can be firmlyattached with the vehicle.

Design headlight type automobile double light: the old product warning light directly after the shot， if the car in a bend in the road or turn when，after the car drivers will not see the warning light， the light is arranged onthe two sides of the rear shark antenna， the design not only solves the defects， and beautiful appearance.

Transparent position brightening Spotlight: design similar to that of convex lens can spot LED lamp round is divided into a plurality of sections pullstrip， which increases the brightness of the warning， and can guaranteeafter the car driver close to the rear lights not dazzling， and after the car driver to avoid unnecessary disputes.
