I keep a pretty close eye on air traffic over my house. I noticed that just about every airline that flies over (American, Southwest, ASA, Skywest, Frontier, FedEx, and Airborne) do not have their tail logo lights on. Because of this, only the front half of the plane is illuminated. However, Continental from EWR flew over last night, and he had his logo lights on. The entire aircraft was lit up. What is the reason for some airlines using these lights, and some not?

Thats interesting...Almost every 737-NG that comes into SJC has there tail light on...Ever since that last thread regarding this issue, it seemed that more pilots are using the lights...Still haven't seen a 300 with them on though...

If they are installed they´ll have to be servicable or deferred with a time limit as per MEL. Now getting up there to change a light bulb typically requires a cherry picker (access is often from the bottom of the horizontal stab, exception B737 with the logo lights in the wing tips). So they create some maintenance issues. As a result masny airlines decide to deactivate them permanently and removing them from the MEL.

ASA deactivated the logo lights on their CRJ's for maintenance reasons as MD11Engineer mentioned. They are located on the engine strut and vibration from the engine made the bulbs burn out on a regular basis.

How Reliable are these logo lights,from frequent Alignment/Fusing problems.
Secondly the logo lts can be C/F under MEL.
Thirdly it would be more noticeable on the Grd or at a lower Altitude.
I think most Airlines want to save Money & hence opt out of the Logo light & its support equipment.

Logo lights getting deferred. You must be having a laugh, whenever we get an aircraft in the hangar there is quite often 4 burnt out logo lights with no sign of anything in the tech log. This is mainly because it is not an important part and I think the MEL only gives a 10 day restriction which could be a bit tight, so they are usually seen to be working when on the line. The trouble with the 757/767 is that the logo light filaments are replaced from on top of the stab which is even worse than on the 737NG which is from a panel underneath the stab.

On the ERJ, I work on, it´s a MEL D item. So we have up to 120 days to fix it. Its a real sh!t. I believe first the took the lamp, then they installed the two wires and then the horizontal stabilizer was riveted around. You need a gynaecologists fingers to attach the wires to the lamp.

I am pretty certain our aircraft aren't on a 10 day restriction to be honest but I am sure it is less than 120 days but I don't know for sure without looking it up.
On the 757/767 they are easy to change apart from when the terminals fall off in your hand due to corrosion and need a new one crimped on which means a trip down to get the terminals and tools needed then back up again to cut your hands on all the broken glass from previous filaments that have cracked and fallen apart.

We had logo lights on our 737-800 when we first got them. However as time went on they started to become a pain and the decision was made to deactivate the system. Can't say that I miss changing those lights out.

I am actually the opposite to you LMP as I find the logo lights really easy to change on the -800 as you can get to them from underneath the stab and there is only two to burn out as opposed to 4 on the 757/767. Also with them being halogen filaments on the -800 as opposed to regular sealed beam lamps they dont seem to burn out as much.
Now the worst lights to change have to be the red and the green nav lights on a -800 with winglets as you have to remove the whole of the lens assembly which is held in with quite a few screws. It is such a pain to do that the AMM actually recommends changing both filaments while you have it out. This is only the aircraft fitted with Aviation Partners Boeing winglets as I have never worked on one with the Boeing factory fit winglets but I doubt they are very much better.

I just love the jokers who on big checks put sealant around the access panels for nav lights!
I think they are the same guys who force all these panel screws with the worn recess back in! $$%&§
Most nav light repairs on the 727 are very easy:
You are sitting in your truck, waiting for departure. The F/E comes back from his walkaround and tells you that a wing tip nav light isn´t working. You ask him to show you which and walk with him to the offending light. There you´ll take the rubber traffic cone from the tarmac under the wing tip and give the wingtip a good whack with it, and enjoy the shocked look on the F/E´s face. And ... Bingo, the light is on again.
The reason is that the contacts in the lightbulb fitting tend to oxydise on this design. The vibrations from the whack break down the oxyde layer and the current can flow again!
Only if the whack doesn´t help you´ll get out the ladder and the screw driver to change the bulb. In 99% of all cases it is then at fault (burned through), in the one percent left, it is the lightbulb fitting.

On my corporate 737-200. The Big Boss loves them on/working,while the whole flight dept. doesn't. The locals have already taken some shots at us with a shotgun when we come in late(r) at night. We even had one drunk redneck show up at the airport waving his shotgun around!! Whoever said this job was boring?
