Abstract
The invented device is composed of detector and alarm, and is characterized by that it only has need of inserting detector into the position of original signal lamp output interface, and connecting the alarm to two ends of automobile power supply, and has no need of changing any wiring and structure on the automobile, so that it can implement the above-mentioned functions for existent vehicle. The driver can drive with attention, and fine or traffic accident caused by not finding the damaged tail lamp can be avoided.
Description
The utility model belongs to the fault alarm field, or rather, and the warning device when being a kind of automobile signal lighting fault.
Running car is realized the illumination in night by signal light, and is sent motion signals at once such as brake, turning, in case taillight damages, as can not in time find, change, light fine then, heavy then can lead to traffic accident, driver's drive often will take into account quality of taillight, the attention that influence is driven.
The purpose of this utility model is will provide a kind of existing vehicle condition is not made any changes, and dismounting is extremely convenient, in case the car bulb accident warning device that taillight breaks down and promptly can report to the police and inform.
The utility model is finished as follows: the utility model is made up of detector and annunciator, detector input end A
1(Fig. 2 is inserted in automobile signal flasher output line interface A place.The former automobile signal flasher that is inserted in automobile signal flasher output line interface A is imported socket B, is inserted in the output interface B of detector

4Demodulation of frequency discriminator goes out peculiar signal and through IC
5Be amplified to buzzer and report to the police, after changing the bulb, IC
2Failure of oscillation, warning stop.
After implementing the utility model, the driver needn't care for the taillight quality, the driving of can focusing one's attention on.Avoid not changing, and cause fine and traffic accident because of knowing that taillight does not damage.
Simultaneously, existing automobile does not need to change the wiring of any structure on the automobile when increasing the utility model, only need detector of the present utility model is got final product by (comparison diagram one, figure two) in the middle of being inserted in original lamp wiring socket, and annunciator can be convenient by the driver, is connected on any automobile power source end.The utility model price is very cheap again, thereby is easy to implement on existing automobile.
