how can i change the speedo bulb on a peugeot 406?

Remove the three screws at the top of instrument panel now gently prise away the plastic shroud .Now unscrew the four screws two at top and two at the bottom,now gently prise the clips and pull panel forward to get to the bulbs. drop the steering wheel down as far as you can for better access.Good luck
