켜져요
켜져요 means “comes on” or “is lit” here, so 불이 안 켜져요 says that the light does not come on. It is the polite form related to 켜지다 and is used after the thing that comes on. In this scene, it is used to report a light problem.
스위치를

오래됐을지도 means “might be old” here and presents the bulb’s age as a possibility. It is related to 오래되다 and is completed by 몰라요 in 오래됐을지도 몰라요. Use this exact possibility expression when you are not certain about the cause.
몰라요
몰라요 means “don’t know,” but here it completes 오래됐을지도 몰라요 to express “may” or “might.” It is the polite form related to 모르다. The possibility meaning belongs to the full 오래됐을지도 몰라요 construction, which is useful when offering a possible explanation rather than a definite one.

가져올
가져올 means “bring” in 가져올 수 있어요, the action that is possible. It is the form related to 가져오다 used before 수 in this ability expression. Use it with an object when saying that you can bring something.
수
수 is the possibility or ability part of 가져올 수 있어요. It works with the following 있어요 rather than standing alone. This construction is used when the speaker says that an action can be done, here bringing a small lamp.
있어요
있어요 means “can” here because it completes 가져올 수 있어요. It is the polite form related to 있다, but the meaning “can” belongs to the full 가져올 수 있어요 construction. Use that expression to offer or describe a possible action.
나중에
나중에 means “later” and places the bulb change at a later time in 나중에 전구를 바꿔야 해요. It comes before the action. Use it when an action is planned for a time after now rather than immediately.

해요
해요 is related to “do” in form, but here it completes 바꿔야 해요 to express that changing the bulb is necessary. It is the polite form related to 하다. The obligation meaning comes from the full 바꿔야 해요 construction, which is useful for stating a required action.
바꿀
바꿀 means “replace” or “change” in 바꿀 때까지, referring to the replacement of the bulb. It is related to 바꾸다 and comes before 때까지 to mark the action that sets the endpoint. Use the full 바꿀 때까지 expression when describing what continues until a change happens.
때까지
때까지 means “until” and marks the endpoint in 바꿀 때까지. It follows the action phrase that identifies what must happen first. Here, the lamp is used until the bulb is changed; a reusable pattern is an action followed by 때까지.
사용하세요
사용하세요 means “use” as a polite instruction in 램프를 사용하세요. It is related to 사용하다 and is used when telling someone what to use. Here, B gives practical advice for the period before the bulb is replaced.
