Luton, Dunstable and Leighton Buzzard joined together on Saturday night to raise over £3,000 for a Good Samaritan.
Keely Adams, 47, of Leighton Buzzard, lost her leg and was confined to a wheelchair, when she was hit by a HGV lorry in November.
The mum-of-two and her partner, Matthew Shaw, went to the aid of a couple trapped in a crashed car in Stanbridge Road.
While Matthew tended to the couple, Keely tried to warn oncoming traffic of the dangers but was clipped by a lorry which ran over her leg.
Her leg was too badly injured for doctors to save and she had to have it amputated.
The lorry driver has not been found and Keely is now not working as a result of her injuries.
The event was at the Conservative club, Dunstable and organisers received more than 50 raffle prizes from local businesses and donations from organisations.
Luton councillor Tom Shaw, Matthew’s father, said: “It was a very good night, I can’t thank the manager and staff at the Conservative club enough, they gave us the hall and the DJ for nothing, they really were fantastic in everything they did for us.
“The amount of people that turned up was overwhelming, you couldn’t have fitted another person in there, you had people from Leighton Buzzard, Luton and Dunstable.
“It was really nice to see so many people there, supporting Keely, it was a real community event.
“Keely is doing really well, she is a strong girl and she is grateful for all the money raised on Saturday.
“The money raised will help her with general things and we hope to fit equipment in the house to make things easier for her.”
“She is going to get the fitting for her prosthetic leg this week,” he said.
