I just thought of this tonight. When the lights are turned on in the airport grounds (twys, aprons, rwys.....), is there a hazard of an a/c rolling over the light and smashing it? Probably not, so what's the scoop? Are the lights buried underneath the tarmac and have a transparent "cover" over them? Or is it more complicated? Info is appreciated

Light on the taxi and runways are inbedded however there is a little bump when you taxi over them which will not damage the aircraft, however make the ride uncomfortable, for this reason the lights are slight off center line.
The only lights that stick out of the groud are the blue taxiway edge lights, the do occasionally get broke when some one mis judges a corner.

If you ever hear an airline pilot use the phrase "killing turtles" you'll know they mean. Heading down the runway hitting all the lights makes a thump-thump-thump sound. It's a little more noticeable in the cockpit because it's right above the nose gear.

The visible portion of the in-pavement light is a steel cover that does indeed resemble a turtle's shell. There is a thick lens on one or both sides of the cover depending on the application with a bulb and color filter inside. The light is only visible from the desired direction of travel and can be different colors on each side. The cover is bolted to a "can" imbedded in the runway surface which contains power supply wires and a transformer. These covers take a beating from all the traffic and can come loose on occassion. This is one of the things the airport operation people look for during runway inspections and during runway closures.

I can tell you, running over the runway lights at SIN in a Lufthansa Airbus A340 at 290km/h is not a fun experience.
Our captain was very precise, however he also flew down the runway exactly over the runway lights, which meant a lot of banging in the cabin - you could watch the overhead lockers dancing as we approached Vr.
