Proposal

This tag is to be used with flashing_lights=yes to indicate the precise design of the flashing lights.

This will also allow traffic_sign=* + flashing_lights=yes to indicate that a flashing light is integrated of placed on the pole of the traffic sign. Up till now, flashing_light=* is only used in the context of a highway=crossing

Some types of barriers (such as barrier=traffic_calming or barrier=sump_buster might also have flashing lights, and will get flashing_lights=*

Rationale

There are multiple types of flashing lights in use - sometimes even with legal repercussions. Sometimes, contributors want to tag the type of flashing light and abuse crossing_ref=* for this (e.g. crossing_ref=hawk or crossing_ref=rrfb as used in the US, hence poluting that tag.

Tagging

Caption text
Tag Applicable country Description Image
flashing_lights:design=belisha_beacon UK, Ireland, Common Wealth A Belisha beacon (/bəˈliːʃə/) is a yellow-coloured globe lamp atop a tall black and white striped pole, marking pedestrian crossings of roads.
flashing_lights:design=standard * A plain, orange flashing light. Note that the signal face (the drawing on the light) is not relevant for this tag.
flashing_lights:design=traffic_sign * The flashing lights are integrated into the traffic sign
Flashing lights integrated in a traffic sign
A flashing light mounted just above the traffic sign
flashing_lights:design=rrfb US "rectangular rapid flashing beacon
flashing_lights:design=road_surface_bulbs flashing_lights:design=road_surface_strip * There are flashing lights embedded in the road surface, either as bulb or as a led-strip. Might also be found around barrier=traffic_calming or barrier=sump_buster objects (Note for the proposal - I've used 'road_surface' as 'pavement' is american english and can be confused with sidewalk; i've also opted for _bulbs and _strip, as this felt more as a design instead of a location)
Please, add relevant examples

Possible tagging mistakes

HAWK-beacons (US)

The hawk-beacon functions as a traffic light, except that it has flashing red/amber instead of green/orange/red. Cars must stop in one phase and are allowed to continue in another phase. As such, traffic_signal=hawk is more appropriate.

The first mention of flashing_lights:design=* was mentioned in this forum post. Earlier posts in the thread mention the desire for this tag, albeit with a different key.

Out of scope

Signal face

The signal face is the icon on the traffic light or the flashing light. It typically depicts a pedestrian, a cyclist, a car or an arrow. Signal faces can be implemented by painting on the traffic signal, by using a removable lens or by having the light itself be constructed out of multiple small LED-lights, in a certain pattern.
