Someone correct me if im wrong...but itsnt it a requirement for commercial passenger planes to have wing tip strobe lights? Is it just a requirement if it was built after a certain date? It was an old 727 that I noticed at work today that didnt have them and was just curious. Any info is appreciated....

Every 727 I have ever been on (usually TWA and some AA) have always had strobes on. Infact they had a front and rear mounted seperate strobe that blinked individually. Might just be a possibility that they had them switched off. Pilots will do this while on the ground obviously, and a lot of times while flying through clouds or foggy conditions. This might not have been your case but im just tryin to think of some possibilities.

I watched the aircraft come in from a left base all the way to the ground and it did not have strobes the entire time. As to looking it up....im too lazy lol. I thought maybe the smart and knowledgable people of airliners would know this! Oh well..thanks for the replies so far!

Here's what the FAR's state for operating an aircraft.
§ 91.209 Aircraft lights.
No person may:
(a) During the period from sunset to sunrise (or, in Alaska, during the period a prominent unlighted object cannot be seen from a distance of 3 statute miles or the sun is more than 6 degrees below the horizon)—
(1) Operate an aircraft unless it has lighted position lights;
(2) Park or move an aircraft in, or in dangerous proximity to, a night flight operations area of an airport unless the aircraft—
(i) Is clearly illuminated;
(ii) Has lighted position lights; or
(iii) is in an area that is marked by obstruction lights;
(3) Anchor an aircraft unless the aircraft—
(i) Has lighted anchor lights; or
(ii) Is in an area where anchor lights are not required on vessels; or
(b) Operate an aircraft that is equipped with an anticollision light system, unless it has lighted anticollision lights. However, the anticollision lights need not be lighted when the pilot-in-command determines that, because of operating conditions, it would be in the interest of safety to turn the lights off.

I checked the Minimum Equipment List for the 737 (which includes the NG) and it states that one bulb must be working for the green, red and both white wing tip navagation lights, for night flights. The strobe light on the 737 wingtip is an option, and not required for flight. You can also dispatch with one anti collision "strobe" light inoperative (installed on the upper and lower fuselage).

In a nutshell the FAR's state that an aircraft has to have some sort of anti-collision light on during movement. Most aircraft usually have a red rotating beacon. Strobes are usually just an extra measure, but can also be the only anti-collision light if need be.
