     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0018]     Referring to  FIGS. 1, 2  and  3 , an illuminating device capable of being a vehicle headlight and a flashlight according to the present invention comprises a lamp unit  1 , a handle unit  2  and a lamp mount  3 . The lamp unit  1  further comprises a transparent front cover  10  for protecting the light bulb housed therein. The rear end of the lamp unit  1  is provided with a recess  11 , which further includes a pair of first conducting plates  12  located on an inner wall of the recess  11 . An annular groove  13  is formed around the inner rim of the recess  11 , and a pair of first teeth  14  is formed on the rear wall of the lamp unit  1  around the recess  11 . Two breaches  15  are formed on the rear wall, 180 degrees apart and deep down to the annular groove  13 . Further, the lateral wall of the lamp unit  1  is provided with a first hanger slot  16 . The handle unit  2  can be connected to the rear end of the lamp unit  1 . The front wall of the handle unit  2  is provided with a pair of first indentations  20  and a first projected head  21 . The first projected head  21  further includes a pair of first slots  22 , each containing one of a pair of second conducting plates  23 . The lateral wall of the projected head  21  is provided with a pair of second teeth  24 . Further, the rear end of the handle unit  2  is provided with a second hanger slot  25 . The lamp mount  3  can be connected to the rear end of the lamp unit  1 . The front wall of the lamp mount  3  is provided with a pair of second indentations  30  and a second projected head  31 . The second projected head  31  further includes a pair of second slots  32 , each containing one of a pair of third conducting plates  33 . The lateral wall of the second projected head  31  is provided with a pair of third teeth  34 . The bottom side of the lamp mount  3  is attached with a bracket  4 , which bracket  4  is provided with a plurality of through holes  40  for retaining itself on a vehicle body.  
         [0019]     Refer to  FIGS. 2, 3 ,  4 ,  5  and  6  for the use of the illuminating device as a flashlight. The front end of the handle unit  2  is inserted into the rear end of the lamp unit  1 , namely, the first projected head  21  of the handle unit  2  being inserted into the recess  11  of the lamp unit  1 . Thereby, the second teeth  24  on the projected head  21  of the handle unit  2  are engaged with the breaches  15  of the lamp unit  1  and reach within the annular groove  13 . A relative rotation between the lamp unit  1  and the handle unit  2  is urged for 90 degrees, as shown in  FIGS. 4 and 5 , whereby the second teeth  24  of the handle unit  2  will be sliding along the annular groove  13 , and whereby the second teeth  24  are away from the breaches  15 . Therefore, the connection between the lamp unit  1  and the handle unit  2  are secured. Meanwhile, the first teeth  14  of the lamp unit  1  situate in the first indentations  20  of the handle unit  2 , further retaining the lamp unit  1  and the handle unit  2 . Further, the first conducting plates  12  within the recess  11  are coupled with the first slots  22  of the handle unit  2 , whereby two sets of conducting plates  12  and  23  are held in an electric contact. Since the handle unit  2  can be held by a hand, the combined structure is a flashlight. Since the lamp unit  1  and the handle unit  2  are respectively provided with hanger slots  16  and  25 , a strap can go through these hanger slots  16  or  25  to form a suspending belt. To dissemble the flashlight, a backward rotation between the lamp unit  1  and the handle unit  2  is applied for 90 degrees, whereby the second teeth  24  are again aligned with the breaches  15 , and the lamp unit  1  and the handle unit  2  can be pulled apart.  
         [0020]     Refer to  FIGS. 7, 8 ,  9  and  10  for the use of the illuminating device as a vehicle headlight. The front end of the lamp mount  3  is inserted into the rear end of the lamp unit  1 , namely, the second projected head  31  of the lamp mount  3  being inserted into the recess  11  of the lamp unit  1 . Thereby, the third teeth  34  on the second projected head  31  of the lamp mount  3  are engaged with the breaches  15  of the lamp unit  1  and reach within the annular groove  13 . A relative rotation between the lamp unit  1  and the lamp mount  3  is urged for 90 degrees, as shown in  FIGS. 9 and 10 , whereby the third teeth  34  of the lamp mount  3  will be sliding along the annular groove  13 , and whereby the third teeth  34  are away from the breaches  15 . Therefore, the connection between the lamp unit  1  and the lamp mount  3  are secured. Meanwhile, the first teeth  14  of the lamp unit  1  situate in the second indentations  30  of the lamp mount  3 , further retaining the lamp unit  1  and the lamp mount  3 . Further, the first conducting plates  12  within the recess  11  are coupled with the second slots  32  of the lamp mount  3 , whereby two sets of conducting plates  12  and  33  are held in an electric contact. Since the lamp mount  3  can be held by a hand, the combined structure is a flashlight. To dissemble the flashlight, a backward rotation between the lamp unit  1  and the lamp mount  3  is applied for 90 degrees, whereby the third teeth  34  are again aligned with the breaches  15 , and the lamp unit  1  and the lamp mount  3  can be pulled apart.  
         [0021]     The present invention is thus described, and it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
