During my trip to SIN last week I noticed that there were no ground marshallers directing my arriving aircraft to its final parking position at the gate. Instead I noticed an LED board on the wall of gate which displayed the aircraft type (77W in my case) with interactive coloured arrows lighting up and directing the pilot to the parking position.
This is the first time I've seen this sort of setup and was curious if this is the norm in Changi right now or was this something else?

Visual docking guidance systems have been around for quite some time.
AGNIS was for a time the most popular, but now a series of devices using Fresnel lenses are the rage.
Unfortunately, there is no standard system so we have to adapt.
*This article on wiki gives a nice introduction to the subject.
... as you can see these systems have been around since the early 1980s - In fact I did an Aero-student presentation to the RAeS on aircraft ground support equipment that included this 'new technology' many years ago!
It's better to ask a stupid question during training, rather than make a REALLY stupid mistake later on!

Well you learn something every day.
I assumed it was standard everywhere.
Here at ARN we have no marshallers at all! Every single parking stand has some sort of electronic guidance. If there is a failure and marshalling is required, someone from airport operations comes out. Usually the Duty Officer, but last week we had a fireman waving the bats.

Quoting ALTF4 (Reply 11): ATL has had them for a long time, at least on most (all?) Delta gates.
Sort of. When I say theat, I mean they're not as high tech as those being discussed that tell the pilot if they are off centerline etc. They are on their own there but it is exactly like a street signal light and is operated by a ramp agent on the ground standing next to the jetway. As the a/c pulls into the gate, there is a steady green; as the nose gets closer to the stop mark it goes yellow, then red when on the mark and at pilot hits the brakes. Every DL gate save for those on C and D have this system.

Western Airlines developed a parking system which did not require a marshaller back in the 1960's. By today's standards it was very primitive and very cheap, but it worked. It was a piece of PVC pipe which hung down from a higher bar on a couple of chains. The captain aimed the center of the windshield toward the center of the pipe and stopped when the windshield made contact with the pipe. You can see this in the following pictures.

HNL has a similar system on Overseas Terminal gates, but ours has lights to guide the pilot onto the center line. Although, the only airline I see using it is HA.
