Read post again, the bulbs in the Bosch unit can be replaced w/o removing the pushbutton control unit. .5 hrs of flat rate time MAX. For the record R & R time of A/C control unit is only .8 hrs & .2 hrs to install bulbs. Even at $80 a hour it doesn't add up to $800 for a new unit. Not every body in this business is trying to make a fortune.
