This product does not have the radio antenna function， please buyers know!

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， self shining in the darkand vibration environment， is automatically extinguished in the light (or in the quiescent state after two minutes will self extinguish).

Check the product please put in the dark and vibration see whether flicker， if not flickermay be chip protection. The tail on the sun or light as a test 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 concept is a naturalfish (including shark fin imitation)， because the fish fin effect， can reduce waterresistance， but also can pose adjustment swimming convenient. The product is installed in the roof of the shark fin is the fish fin function by combining modern aerodynamics and design.

When the automobile movement speed in the air， will pull a long vortex. When the vortexin 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 and pressure 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 driving or driving for a long time after the car drivers， have a habit of numbness on the color， does not causetheir attention; or because of the opposite automobile 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 preventing effect!

This combination， three water-proof design: the product is provided with the vacuumlayer， the water， glue layer three water-proof function， impact force， first stepdecompression layer reduces wash water cannon， the second step， the water will beafter decompression water from the bottom 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 the washing water into the warning light inside， and products can be firmly attached 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 thewarning light， the light is arranged on the two sides of the rear shark antenna， thedesign not only solves the defects， and beautiful appearance.
