i get this beep from the dash and under mileage 1n 2 appears for 1 min or so is this normal

the thing is this noise has always happened but after today i had the dash out changing some dash bulbs and now i have the airbag light on now i changed 9 bulbs in total and unsure if 1 was the airbag one have i moved something or damaged something

any ideas welcome

thanks johno
