do 3 way light bulbs work in any lamp
3-way lamp The center contact of the bulb typically connects to the medium-power filament, and the ring connects to the low-power filament. Thus, if a 3-way bulb is screwed into a standard light socket that has only a center contact, only the medium-power filament operates. In the case of the 50 W / 100 W / 150 W bulb, putting this bulb in a regular lamp socket will result in it behaving like a normal 100W bulb.
Automotive lighting In the United States and Canada since 1986, in Australia and New Zealand since 1990, and in Europe and other countries applying UN Regulation 48 since 1998,[82] a central stop (brake) lamp mounted higher than the vehicle's left and right stop lamps and called a "centre high mount stop lamp (CHMSL)", is also required. The CHMSL (pronounced /ˈtʃɪmzəl/)[82] is sometimes informally called the "centre brake lamp", the "third brake light", the "eye-level brake lamp", the "safety brake lamp", or the "high-level brake lamp". The CHMSL may use one or more filament bulbs or LEDs, or a strip of neon tube as its light source.
Fidget spinner As of 2017, the patent status of the various fidget spinners on the market was unclear.[8]
Traffic light In Australia a white "B" or "T" sometimes replaces the green light indicating that buses or trams (respectively) have right of way.
