 the vast majority of cases incandescent lamps and, relatively rarely, also gas discharge lamps are employed as electrical lighting means. These two types of lighting means have major disadvantages for the stated purpose of illuminating definite regions inside or outside a vehicle.
The principal disadvantage with the use of incandescent lamps is their very high incandescent-coil temperatures which are made necessary by the system for operation and the high thermal loads that occur as a result, concentrated in one place. In addition, the incandescent lamps themselves are relatively large and offer acceptable light efficiency in operation only when they are installed together with an appropriate reflector. The high thermal losses, the size of the incandescent lamps and the use of reflectors give rise to a minimum size of such lighting devices, which cannot be reduced. This minimum size renders difficult the integration of this lighting device into subassemblies that are present on the vehicle, such as, for instance, the outside mirror, the inside rear-view mirror, vehicle sheets (panels), bumpers, trim strips, covers, consoles, shelves, glove compartments and ashtrays.
For this reason, in many cases the lighting devices have to be arranged in places that are unfavorable for the emission of light, since only in such places is the requisite space available for mounting of the lighting device. Since the size proportions are different in every vehicle, no universally applicable lighting devices can be employed that are economical to manufacture on an industrial scale, but rather a vehicle-specific lighting device has to be developed and manufactured for each type of vehicle. overall, the creative scope as regards the design of lighting devices of this type is severely limited.
By virtue of the thermal losses of incandescent lamps which occur concentrated in one place, temperature problems arise in the region of the mounting location of the lighting device. As a result of the waste heat that arises, the materials of the surrounding subassemblies are very severely loaded thermally. In order to counteract damage to these materials, use is made of expensive, temperature resistant materials, and elaborate measures have to be provided for the dissipation of heat. Since even these measures would not be sufficient in the case of continuous loading, the maximum amount of waste heat has to be limited, to which end timing devices and/or thermal protection devices have to be provided, in order to switch off the lighting prior to the overheating of components. Besides, after the maximum thermal load has been attained, a long recovery interval is required with a view to cooling the components.

the vast majority of cases incandescent lamps and, relatively rarely, also accelerator dismissal lamps are employed as electrical ignition means. These two types of ignition mean have major disadvantages for the stated purpose of illuminating definite region inside or outside a vehicle. 
 The principal disadvantage with the consumption of incandescent lamp is their very high incandescent - coil temperatures which are made necessary by the system for operation and the eminent thermal loads that occur as a result, digest in one place. In addition, the incandescent lamps themselves are relatively large and offer satisfactory light efficiency in mathematical process only when they are installed together with an appropriate reflecting telescope. The high thermal losses, the size of the incandescent lamps and the use of reflectors give lift to a minimal size of such lighting devices, which cannot be reduced. This minimum size renders difficult the integration of this light device into subassemblies that are present on the fomite, such as, for case, the outside mirror, the inside rear - opinion mirror, fomite sheets (panels), bumpers, trim strips, covers, consoles, shelves, baseball glove compartments and ashtrays. 
 For this reason, in many cases the lighting devices get to be arranged in places that are unfavorable for the emission of light, since only in such places is the needed quad available for mounting of the lighting device. Since the size proportions are different in every fomite, no universally applicable lighting devices can be employed that are economical to manufacture on an industrial scale, but rather a vehicle - specific lighting device have to be modernize and manufactured for each character of vehicle. overall, the creative scope as regards the design of light devices of this character is severely limited. 
 By virtue of the thermal personnel casualty of incandescent lamps which occur concentrated in one place, temperature problems arise in the region of the mounting location of the lighting device. As a result of the thriftlessness heat that arises, the material of the surrounding subassemblies are very severely loaded thermally. In order to counteract damage to these fabric, use is made of expensive, temperature resistant materials, and elaborate measures have to be provide for the profligacy of heat. Since even these measures would not be sufficient in the case of continuous loading, the maximum amount of thriftlessness heat has to be limited, to which end time devices and/or thermal protection devices have to be provided, in ordering to switch off the lighting prior to the overheating of components. Besides, after the maximum thermal load has been attained, a retentive recovery interval is required with a view to cooling the components.
