1 tailing light
Tail lamp brightness requirement is not too high, but to be able to induce a degree of attention, to do with the instructions and warning LED
advantages
A, red and yellow LED technology is very mature.
B, LED small size and convenient, giving designers a great deal of design reverie space.
C, vehicle power supply for low voltage power supply, power supply circuits and simple design.
D, energy saving.
E, LED directional well, within a certain angle, high brightness, warning effect is obvious.
F, long service life.
Disadvantages:
A, a relatively complex drive circuit (with PCB board), designed to bring some form of trouble.
B, LED taillights rate of poor maintenance.
C, spot and have some difficulty (but not difficult)
D, sealing demanding.
E, the price a little high.
In summary LED taillights technology is more mature, has most of the body used by the manufacturer.

2, interior lights
Mainly used for vehicle interior lighting temporary lighting purposes, the color rendering index and color temperature on the requirements is not even a very high brightness is not required.
Advantage
A, white light brightness and color rendering index, color temperature and so entirely appropriate to use in the car a short time.
B, power supply design is simple.
C, LED small size and convenient, giving designers a great deal of design reverie space.
D, energy saving.
E, long service life.
Disadvantage
A, light design with a little bit difficult.
B, not suitable for a long time lighting, lighting if the time to consider a simple thermal design.
C, maintenance of poor performance.
D, point source so that light bulbs look and we used to have a certain gap between people's acceptance of challenge.
E, the price a little high.
In summary, as the interior lighting, LED lighting than traditional certain advantages.

3, the former light
The direction of light before lamps, please refer to a taillight; near focus and far focus lamp light source types are strong, the main role to play in front of the lighting.
Advantage
A, energy saving.
B, power supply circuits and simple design.
Disadvantage
A, heat is complex.
B, brightness below standard.
C, optical design complexity.
D, close focus and far focus light design contradictions.
E, sealing demanding.
F, and poor maintenance.
G, the price is high.
In summary,LED headlamps design as there are many technical issues must be resolved some technical strength.
