Hi All,

Just wondering if anyone knew what the sets of
small orange and blue lights are, on the M4 section approx J1-J3.

From the location, they must be connected with the bus lane, but I
can't imagine exactly what they are.

Are they fixed to the lampposts? If so, I think they pre-date the bus
lane, but I can't remember what they are for.
