The light from the light emitting part 313 is projected to the side of the vehicle, and its function is similar to that of a side indicator light. In order to distinguish the display functions of two different orientations, the first light-emitting element 321 and the second light-emitting element 331 are preferably Produces different shades of light. Specifically, if the bumper light device is installed on a bumper in front of the vehicle, the first light-emitting members 321 preferably emit white or yellow light. If it is mounted on a bumper in the rear, the first lights 321 The piece 321 preferably emits red light. As for the second light-emitting element 331, it is preferable to emit amber light. Therefore, the pole-protection lamp device in this embodiment does have various display functions.

In summary, in addition to the novel structure of the pole light device of the present invention, since the light guide strip 31 has both the main light emitting portion 312 and the side light emitting portion 313, it can be combined with the first light emitting unit 32 and the The cooperation of the second light-emitting unit 33 generates light rays projected in different directions, and functions as a position light and a side indicator light. In particular, in the application of a general pole light device, some need to have both the function of a position light and a side indicator light, and some only need the function of a position light alone, and the position display module 3 of the present invention The design may have different functions because the color light used by the first light-emitting elements 321 and the second light-emitting elements 331 is different. For example, when the first and second light-emitting elements 321, 331 use the same color light, the light guide strip 31 has the function of a position light alone. If the first and second light-emitting elements 321, 331 use different When colored light is used, the circuit can be used to control the pole light device to have the functions of a position light and a side indicator light. The foregoing function is due to the fact that the light guide strip 31 has both the main light emitting portion 312 and the side light emitting portion 313. Therefore, the present invention does have the effect of simplifying components.
