The circuit board 21 is disposed on the base 10, and is located in the chamber 11 of the base 10. The light-emitting elements 22 are electrically connected to the circuit board 21 and are detachably disposed in the two side openings 12 of the base 10.

(13) With reference to FIGS. 4, 5, 7, and 8, each one of the light-emitting elements 22 has a shell 23, a first engaging portion 24, multiple first cushioning lugs 25, a second engaging portion 26, and multiple second cushioning lugs 27. The shell 23 has a bottom surface, a top surface, and a rear surface. The first engaging portion 24 is formed on the bottom surface of the shell 23 and is inserted into a corresponding one of the two engaging grooves 15. The first cushioning lugs 25 are formed on and protrude out of the rear surface of the shell 23. The first cushioning lugs 25 abut a corresponding one of the two retaining walls 14. The second engaging portion 26 is formed on the top surface of the shell 23, and is located above the first engaging portion 24. The second cushioning lugs 27 are formed on and protrude out of the rear surface of the shell 23, and are located above the first cushioning lugs 25. With reference to FIGS. 7 and 8, the cover 30 is disposed on the base 10, covers the top opening 13 of the base 10, and has an inner bottom surface, two baffles 31, and two stopping surfaces 32. The inner bottom surface of the cover 30 faces the inner bottom surface of the base 10. The two baffles 31 are formed on the inner bottom surface of the cover 30 and are respectively disposed adjacent to the side openings 12 of the base 10, and each baffle 31 abuts the second cushioning lugs 27 of a corresponding one of the light-emitting elements 22.

(14) With reference to FIGS. 7 and 8, the base 10 has two first leak-proof grooves 16. The two first leak-proof grooves 16 are formed on the inner bottom surface of the base 10, and are located between the two engaging grooves 15 and the two side openings 12 of the base 10. The cover 30 has two second leak-proof grooves 33. The two second leak-proof grooves 33 are formed on the inner bottom surface of the cover 30, and are located between the two stopping surfaces 32 of the cover 30 and the two side openings 12 of the base 10. Furthermore, the detachable warning lamp has four waterproof strips 40. The four waterproof strips 40 are respectively disposed on the two first leak-proof grooves 16 of the base 10 and the two second leak-proof grooves 33 of the cover 30.

(15) With reference to FIGS. 4 and 5, each one of the light-emitting elements 22 has multiple first deforming spaces 28 and multiple second deforming spaces 29. The first deforming spaces 28 are respectively formed between the first cushioning lugs 25 and the rear surface of the shell 23. The second deforming spaces 29 are respectively formed between the second cushioning lugs 27 and the rear surface of the shell 23.

(16) In assembly, the light-emitting elements 22 are detachably engaged with the base 10 one by one, and then the cover 30 is disposed on the base 10. The light-emitting elements 22 are disposed between the base 10 and the cover 30 for fixing the light-emitting elements 22. In each one of the light-emitting elements 22, the first cushioning lugs 25 abut the retaining walls 14 of the base 10. Each one of the light-emitting elements 22 is pushed by the users. Each one of the first cushioning lugs 25 is deformed and provides a restoring force. The first engaging portion 24 is inserted into the corresponding one of the two engaging grooves 15. Each one of the light-emitting elements 22 is moved out of the base 10 by the restoring force. The light-emitting elements 22 are engaged with and retained on the base 10. The cover 30 is disposed on the base 10 and covers the light-emitting elements 22. The second cushioning lugs 27 of the light-emitting elements 22 abut the baffles 31 of the cover 30. The second engaging portions 26 of the light-emitting elements 22 abut the stopping surfaces 32 of the cover 30. The light-emitting elements 22 firmly abut and are retained below the cover 30.

(17) For disassembly, the cover 30 is detached from the base 10 by the users. The light-emitting elements 22 are detached from the base 10 by the users without a hand tool. Each one of the light-emitting elements 22 is pushed by a hand of the users and is moved. The first cushioning lugs 25 of each one of the light-emitting elements 22 are deformed. The first engaging portion 24 of each one of the light-emitting elements 22 moves out of the corresponding one of the engaging grooves 15. Each one of the light-emitting elements 22 is lifted and is detached from the base 10 manually by the users.

(18) Accordingly, the retaining walls 14 and the engaging grooves 15 are formed on the base 10. The first engaging portion 24 and the first cushioning lugs 25 are formed on each one of the light-emitting elements 22. The light-emitting elements 22 are easy to assemble and detach without the use of a screw and the hand tool. The assembly and the disassembly of the detachable warning lamp are convenient and quick, saving time for assembly and disassembly.

(19) In addition, the waterproof strips 40 prevent the mist or a foreign object from going into the chamber 11 of the base 10. Furthermore, the first cushioning lugs 25 and the second cushioning lugs 27 can be deformed in assembly and provide the restoring force for increasing the assembly stability of the detachable warning lamp.
