Rare UK amber arrow traffic lights in Grimsby, North East Lincolnshire

As you probably know, not many traffic lights in the UK have an amber arrow in addition to a green arrow (these are mainly used to prevent drivers from making illegal turns), and usually, if an amber arrow is used, they're more common as a right turn, and even still, most of them are experimental; only a very small number of them were made permanent due to some drivers being confused by the leaving amber period, well on the ones that have the black roundel with amber illuminated arrow, there is also the Intelligent Amber Arrow too to overcome this concern, which is also rare due to TSEU/Microsense using older LED technology, which meant they were not used outside of the original trial sites. The traffic lights here are the (non-LED) Optic design, some of them on this junction are manufactured by Siemens, however, most of them are manufactured by PEEK.
