Red and Green are to denote right of way.
Red is on the left wing, green on the right.
If you see a plane crossing from right to left in front of you in the air, you'll see a red light and that means he has the right of way, in essence a 'stoplight' for you. There's also usually a white on the tail facing backwards.
Strobelights are just for visibility. Along with the anti-collision lights.
Landing lights are very bright to illuminate the runway environment, and taxi lights are bright enough to illuminate the centerline, etc.
I don't have an attitude problem. You have a perception problem

Quoting ArcticTern (Thread starter): Please let me know why red and why green, strobe, white light, wing inspection, landing, taxi, anti collision
you also have runway turn off lights, these are taxi lights that are angled to the sides, wing inspection lights are to illuminate the wing to inspect for ice in flight!
on the 777 anti col lights are the upper and lower beacon (red) and then strobe lights are the white flashing lights on the wing tips. (i think)

Quoting ArcticTern (Thread starter): On a 777, i have noticed the anti collision lights keep changing. One blink its red and the other blink its white and the cycle continues.
You are confusing the Red Anticollosion lights mounted on Top & Below Fuselage with the White Flashing strobe lights located on Wingtip & Empennage at end of fuselage.

Hi MEL,
I for sure know the anti collison light have two colours, one normal aircraft like the IC320 they are completely red. On the other hand the Boeing 777 has two colours Red and white. There is a cycle of Red-white-red-white.
I have seen them on a Boeing 777, especially on the Singapore airlines.
Thanks,
Sushant
I wanted to fly even before I knew how to pronounce the word 'Pilot'

I'll check it out Tonight if I get the time.The SIA B773 passes thru BOM.
Are you sure the White flashes were from the Top & Bottom of the Fuselage along with the red.

Some aircrafts really have the anti-collision lights which changes color. For example, Saab 2000 does have red anti-collision lights when on the ground and those same lights are white when it is airborne. It does have white strobe lights as well. I believe that the old DHC8-200/300 series aircrafts have similar color changing anti-collision lights too...
On the other hand, ATR72s does have anti-collision lights which are white all the times. I'm not sure about the B777, though!

could this be a customer option?
a BA 777 took off over my head on my way home an i could have sworn it was always red.....or maybe my eyes are playing tricks on me?

Quoting HAWK21M (Reply 8): Whats the Mechanism used.Is it a seperate Bulb in the Circuit.
I'm not sure, MEL. However I believe that it might have something to do with anti-skid controller unit which monitors wheel speed and air/ground logic. That is my best guess...

Good evening!
Hope all of you got to see the 777-300LR taxing. The video is amazing but the lights are confusing. Till date I knew the Anti collision lights were red but now we have a different picture.
For time being can some one explain the lights on the wings, I know port is red and star board is green, i guess they also have strobes and white lights.
Similarly, the tail has a strobe and white light. what are the uses.
Logo light, taxi light, wing lights. I can figure out why they are used
Thanks,
Sushant

i'll give you a quick walk around of a 747-400
ok start at the nose, 4 white lights, two taxi lights and two runway turn off lights on the nose gear.
walk towards the port wing, two landing lights in the leading edge wing root. one icing light just rear of door L2 shining along the wing leading edge
walk to the wing tip, 2 red nav lights and a white strobe. (777's have a steady white nav light on the wingtip trailing edge i believe)
walking towars the tail, theres is about 4 emergency lights over the wing in a line flush with fuselage.
at the tail, 2 steady white nav lights just below the AP exhaust, on a shelf, just below the shelf is a white strobe.
starboard side is the same as port, except nav lights are now green, when i'm at the starboard wing tip i check the top of the upper deck for the upper beacon. then walk to the lower beacon to check for cracks and such.
then if ur interested in the rest of my walkaround, i check gear bay lights 3 in each main gear bay equalling 12 and 2 in the nose wheel bay, then i check ariels and pitot static ports for damage!
forgot to mention, if its dark check logo lights, position on the horiz stab shining at the tail

What are the "emergency evacuation lights"? I assume thy come on in tandem with the interior emergency lighting? Any pics of these exterior emergency evacuation lights?
Remember, taking off is optional, landing is mandatory.
you can see them here, if you look directly below the 5th window back from door R3 and then again below the 8th window, there only small, and just appear to be black marks.
i have a better image saved on my hard drive, but i cant link it on here, if you'd like me to email it to you just ask, and yes, your correct, they work from the emergency lights switch

its actually a pic from airliners, i had a copy at work which i drew red circles around the lights to highlight it, but i'm a bit hesitant to deface and post it as some of the photographers get well arsy with all this copyright bollocks!
so here's the pic, there much clearer, 3 in view, just above the TE flaps
25 Matt72033: cheers MEL, i think there clearest on the VS pic!
26 HAWK21M: Tried searching for a closer image of those lights unsucessfully. regds MEL
27 ZuluAviator994: okay, just an idea on the white/red strobe lights on the 777 maybe its a customer feature or maybe to distinguish the long range varients to the norma
28 Soon7x7: While I sit here and read all these responses, no one is quite sure...but most are correct...my feet are literally resting on 757 and 737 wingtips w/
