Hi,
Yes, the headlights are LED. 109 LEDs in each lamp, actually. Found them on eBay a few years ago, a pair of flashlights costing next to nothing. They are still out there - for example item 350170563886. I had to rewire the LEDs to use it on 24V without too much loss, though.
They look just like Xenon-lamps, which I must admit is not very realistic on a Land Rover. But they provide great light for night driving, and makes the Toylander easy to spot for the other cars on the road.
