The present invention provides a C.I.P. of U.S. patent application Ser. No. 09/546,175, namely, an improved device for the bulb socket. This refers to a jacket set at the caulking part above the fixture of the bulb socket. There are several jack catches inside the jacket. Besides, the outer part of the bulb is added with several convex catches. When the bulb is inserted into the fixture of the bulb socket, the convex catches of the bulb will be geared between the jack catches within the jacket. Such an engagement can fix the bulb with the fixture of the bulb socket more effectively.
