Claim:
A flagpole lamp of a vehicle head comprising: a pole ( 1 ), a connecting member ( 2 ), a circuit board ( 3 ), a positioning base ( 4 ), a waterproof washer ( 5 ) and a pole head ( 6 ); wherein the connecting member ( 2 ) is fixed on the pole ( 1 ), a laddered chamber ( 21 ) formed inside it, a through hole ( 22 ) formed in the bottom of the laddered chamber ( 21 ), and female threads ( 23 ) formed around the inner wall of the laddered chamber ( 21 ); the circuit board ( 3 ) is installed in the laddered chamber ( 21 ) of the connecting member ( 2 ), provided with at least one luminous body ( 30 ) able to alter light color thereof, a power line ( 31 ) connected to the circuit board ( 3 ), and at least one through hole ( 32 ) each inserted with a screw ( 33 ); the positioning base ( 4 ) is installed in the laddered chamber ( 21 ) of the connecting member ( 2 ) and fixed on the circuit board ( 3 ), provided with at least one through hole ( 40 ) and at least one threaded hole ( 41 ); the waterproof washer ( 5 ) is located on the positioning base ( 4 ) inside the laddered chamber ( 21 ) of the connecting member ( 2 ); the pole head ( 6 ) is mounted on the connecting member ( 2 ), formed as a light-transmitting object, and male threads ( 62 ) formed around its lower outer surface; and wherein in assembly, firstly the circuit board ( 3 ) is placed under the positioning base ( 4 ) with the at least one luminous body ( 30 ) of the circuit board ( 3 ) extended up through the at least one through hole ( 40 ) of the positioning base ( 4 ); then, the at least one screw ( 33 ) extends through the at least one through hole ( 32 ) of the circuit board ( 3 ) to keep it engaged with the at least one threaded hole ( 41 ) of the positioning base ( 4 ), so as to fix the positioning base ( 4 ) on the circuit board ( 3 ); next, the circuit board ( 3 ) and the positioning base ( 4 ) are placed in the laddered chamber ( 21 ) with the power line ( 31 ) of the circuit board ( 3 ) passing through the through hole ( 22 ) of the connecting member ( 2 ); then the waterproof washer ( 5 ) is installed within the laddered chamber and located upon the positioning base ( 4 ); and then the pole head ( 6 ) is mounted on the connecting member ( 2 ) by engaging the male threads ( 62 ) with the female threads ( 23 ) of the connecting member ( 2 ) to keep the pole head ( 6 ) fixed on the connecting member ( 2 ) firmly with the bottom of the pole head ( 6 ) pressing on the waterproof washer ( 5 ); thus finishing the whole assembly.
