I had a passenger seat side airbag in a Ford Galaxy go off a few years ago after driving into a pot hole in the dark. Scared the bejezus out of me.
The cost of replacing it was extortionate so I wired a 2 ohm resistor into the end of the airbag multiplug. This allowed the light to go out and retained the functionality of the front airbags.
Not sure I'd do it on a front airbag although I discovered its a common "get around" when replacing an airbag steering wheel with an aftermarket one.
