12v Amber Multi Function Multi-LED Beacon (West Bletchley MK3)
Plugs into a standard 12v power/cigarette lighter socket. Has multiple flash sequences controllable from the 12v plug. Whether it's legal to use this to warn other motorists of your presence in an emergency in this ridiculously over-regulated country is debatable so I'm covering myself by saying it's for offroad use only... Found it in the loft, I don't need it.
