Any vehicle has the potential to catch fire. Me and my nana was involved in such an incident in the early 90s when a Northumbria bus went up near Whitley Bay Ice Rink. Still never put me off.

There has been two Streetdecks that has caught fire one mechanical in Southampton the other was malicious in Northern Ireland.

It's possible Streetlites have also had thermal incidents, though most modern vehicles should have fire suppression systems to try and reduce the damage.
