Allira I grew up in Blackpool and the queue for the lights used to be extremely long on Squires gate Lane, just before the start on the prom at Starr Gate.
There was even a phrase 'beat the peak, come midweek!'. 
Day trippers, well evening trippers really, would start to form the queue as soon as it was dusk- drive along the prom through the lights- then drive out of Blackpool using Preston New Road. So you could just drive through and leave again,
It was a one way system- very disruptive for Blackpool residents who avoided the prom like the plague if they wanted to get anywhere quickly.
This was before the M55 motorway was built which enabled many more to have speedy access to Blackpool, just for the day/evening.
The weekends were when lots of coaches etc came and people stayed in the guesthouses and hotels, so the lights were a great way of extending the season, leading nicely into those who came for Christmas and New Year.
We moved down south about 30 years ago and when we go back to visit relatives I hardly recognise the place, so many new roads in and out, connecting with the M55, new builds where the countryside was ( yes even up North we had fields and cows
) and its lovely to see the tower still standing proud, shining like a colourful beacon.
