Under normal working conditions, it shall not interfere with the illuminating position of the headlamp beam of the motor vehicle.
1. Motor vehicles equipped with headlamps shall be equipped with a device for converting the upper beam and the lower beam. When the upper beam becomes the lower beam, all the upper beams shall be extinguished at the same time. The headlamp of the same vehicle shall not be switched on alternately with the low beam lamp and the left and right low beam lamps.
2. The four lamp headlamp installed inside or on the top corresponds to the single beam headlamp.

Product Design
1.The first beam sustain a lot of pressure , this physical design is important in safety and practicability, we use 3mn thicken steel plate , it is exactly bear the pressure but not waste power. It drastically solve the problem
2.Plus size frame Surface treatment: pickling, phosphating, electrophoresis high-temperature baking design, its own outfall , thicken keel are extend to frame it improve frame ruggedness
3.Augmentation : it is a device to change the torsion , it can widely use in different road condition it make tricycle more easy t on uphill
Quality assurance
1. Material technology: We will select 5-10 products that meet our standards from 100 steel products, and the remaining materials will be supplied to factories of other second and third-tier brands. Only those that meet the thickness, size and material we just mentioned can pass our screening. And our frame production line consists of 18 processes.
2. Pneumatic fixture is also used in our production process to ensure stronger welding strength and better consistency. The production of the fixture refers to the automobile standard and has obtained a number of patents.
3. Carriage welding: 90% of carriage welding is made by CNC robot welding, with better quality and more smooth and beautiful welding points.
