Hello, daylight.
The model as delivered is not illuminated; the lamps are strictly cosmetic. There is a vendor, however, offering upgrading which includes DCC, sound and lights. Here's a video of the upgraded Blue Peter. The sound is something to behold for such a small model.
By the way, if you'd like to order Blue Peter, I wouldn't delay as the Bachmann UK website is showing the 60532 version already sold out. Hatton's still has it in stock.
Best regards,
Bob
