In assembly, as shown in FIGS. 1 ̃4, firstly fit the waterproof ring 53 around an upper end of the lucent bar 4, and then insert the central tube 45 into the through hole 40 of the lucent bar 4. Secondly, fix the upper circuit board 50 and the lower circuit board 51 respectively in the chambers 41 and 42 of the upper and lower portions of the lucent bar 4 by the screws 502 and 512, with the luminous bodies 500 and 510 of the upper circuit board 50 and of the lower circuit board 51 respectively fitted in the recesses 410 and 420 of the chambers 41 and 42, and with the power line 52 connected between the upper circuit board 50 and the lower circuit board 51. Thirdly, engage the lower bar 3 with the lower portion of the lucent bar 4, Fourthly, fit the waterproof ring 25 in the groove 23 of the lower connecting member 2, place the conducting plate 26 in the chamber 21 of the lower connecting member 2, and engage the lower connecting member 2 with the lower portion of the lower bar 3, with the conducting spring 513 and the conducting connector 514 of the lower circuit board 51 contacting with the conducting plate 26, and with the bottom of the lucent bar 4 pressing on the waterproof ring 25. Fifthly, insert the positioning base 7 into the chamber 61 of the upper bar 6, and then engage the upper bar 6 with the upper portion of the lucent bar 4, with the power line 71 passing through the through hole 62 of the upper bar 6 to be connected with the upper circuit board 50. Sixthly, place the waterproof washer 72 on the top of the upper bar 6, and then engage the upper connecting member 8 with the top of the upper bar 6, with the at least one luminous body 70 of the positioning base 7 fitted in the through hole 82 of the upper connecting member 8. Seventhly, mount the pole head 9 on the upper member 8, with the projection 81 of the upper connecting member 8 fixedly inserted in the recess 90 of the pole head 9. Finally, insert the projection 20 of the lower connecting member 2 into the pole 1 to finish the whole assembly of the invention.
In using, as shown in FIG. 5, the pole 1 is positioned respectively at two corners of a vehicle head (A1) of a vehicle (A), with the power line 27 of the lower connecting member 2 connected to a lamp control circuit of the vehicle (A). When a driver turns on headlights (A2) (main ones or small ones) of the vehicle (A) in the night or in the dark, the luminous bodies 500, 510 and 70 of the upper circuit board 50, of the lower circuit board 51, and of the positioning base 7 can all be simultaneously actuated to emit colored lights (such as blue one). By the time, the luminous bodies 500 and 510 of the upper circuit board 50 and of the lower circuit board 51 emit a colored light toward the lucent bar 4 to be reflected by the electroplated surface of the central tube 45, keeping the lucent bar 4 fully shined; the at least one luminous body 70 of the positioning base 7 emits a colored light upwards capable of transmitting out of the pole head 9 to keep the pole head 9 as well shined. So, the driver can clearly see the corners and the position of the vehicle head (A1) to prevent any collisions from happening. Also, the pole head 9 has an aesthetic figure. Moreover, when a driver intends to make a turn with the directional lights (A3) turned on, the luminous bodies 500, 510 and 70 of the upper circuit board 50, of the lower circuit board 51 and of the positioning base 7 can be as well automatically actuated to flashily emit another colored light (such as orange one) capable of respectively transmitting out of the lucent bar 4 and the pole head 9 to attract attention of drivers of other cars running beside and behind the vehicle (A) for enhancing traffic security.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
