For example, the exterior headlamps, tail lamps, emblems, etc. are made to shine brightly, and the interior surfaces are brightened to make it easier to see the various instruments in the driver's seat. . Taking as an example the rear panel garnish a of the car C 1 shown in Figure 1, the letter b is displayed and illuminated by a transparent body c [its thickness]. The light-emitting bodies d and d' are attached to the vehicle body through a plate ( t1 is thick and flexible), and are further fixed to the vehicle body by a mounting plate e.
