Didn’t have many sets with lights myself, but the ones I had felt so SPECIAL.

Look, he's taking an extreme closeup of the pavement with one of those antique bellows cameras!

I can’t hate it, (the dozer looks great in my opinion), but I don’t like the focus on the lighting system. Makes the set look less desirable.

Do two people count as a crew? I feel that’s barely a team never mind a crew

"They really should go back to the two-wire 9V system for basic PF uses. The PU system is such a major mistake - expensive, over-engineered, bulky, inflexible and even needs an app. Trivial tasks like extending cables, connecting two devices to the same channel or reversing motors are nearly impossible, even connecting a device to a spare channel is enough to make it crap out. And while the old systems teached the basic concepts of electric circuits, the new ones only teaches you to be a passive consumer."

I definitely agree - a simple light & sound system based on a small battery box would be really great in City and perhaps even some Creator sets.

This was one of my favourite sets growing up. First, because I liked yellow construction sets, and because the light-up signs seemed so clever, and lastly because it was one of the few sets I managed to get not at Christmas/Birthday time.

Ah! I remember drooling over the pictures of this set in the catalog as a kid. Just like @Zordboy , I never owned this one but got the police van instead - and loved it as well. Still have it and I am amazed that these tiny Lego light bulbs from the 80s are still working.

Maybe I should just pick this one up somewhere and satisfy my 30 years lasting nostalgia hunger.

I didn't know there was a yellow 9V battery box in the Light (& Sound) System. I've used one to power Wall-E from LEGO Ideas, works like a charm, great battery box indeed.

I recently picked mine up from storage. Amazingly all electronics still work perfectly.

Oh the memories with this one! The yellow battery box is still in use in a large airport fire fighting machine I built 20 years ago. It has 9 lights and a siren and everything still works.

I also recently dug the electronics from my old 6750: Sonic Robot out of our specialty pieces bin. They, too, work perfectly! It certainly was/is a great system.

@Paski:
It really depends on how often you run them, and for how long at a time. One of the guys in my LUG built a hospital with a helipad on top. Surrounding the helipad, he has four of the two-bulb elements, set to blink in alternating patterns. Over the course of maybe one year, they started failing, resulting in one fully functional, one completely dead, one with the left bulb burned out, and one with the right bulb burned out. As a result, he could arrange them so that only the four forward bulbs would blink, and the four in back wouldn't light up at all.

Ever heard of a cockpit crew?
When I hear crew I automatically think of two people whereas a team usually tends to be at least three or four people.

Anyway, love the old light and sound system. I have several of those sets, and all of them still work. The whole concept is so cool with those plates with metal contacts inside. TLG would never do anything like that again nowadays, for fear that kids would be so stupid as to harm themselves with those pieces in some obscure way.
In that regard, growing up in the Eighties was bliss. :-)

If it's anything like any roadwork crew around here (especially town/county employees)--you've got those two working, and then another 3-4 guys hid behind the truck taking a smoke. No wonder it takes them months to do a simple project!

The loader is designed well, the compressor/generator trailer is designed well. 9V is a "KISS" system; since you don't have all the sensors and stuff of PU to go wrong. Aside from bulbs (which always tend to die at the least expected moment--especially these pre-LED bulbs) they will work as long as you've taken the batteries out. My PF works even when stored in a damp basement.

https://en.wikipedia.org/wiki/Aircrew

On commercial aircraft, I count no less than 13 potential positions, some of which (like "relief crew" or "flight attendant") can require multiple people to serve in the same role. On a military aircraft, there are 21 potential crew positions listed. In this case, while some (air gunner) can again consist of multiple positions, several of these are limited to specific types of aircraft, so no single aircraft would have all of these crew positions represented.

When I think of "crew" vs "team", a crew performs manual labor or operates a vehicle of some sort, while a team is either white-collar work or sports that don't involve vehicles.
