To change the bulb in the Pfaff Tiptronic 2030, you need the bulb remover that was in the original accessory package. Push the bulb remover up into the sewing machine (at the bulb) as far as it will go. Rotate the tool (and the bulb) one-half rotation counter-clockwise. Bring the tool and the bulb down and remove the bulb from the remover tool. To put the new bulb back in, put it into the diagonal holder until the pins engage. Push the bulb up into the lamp holder of sewing machine as far as it will go. Rotate the bulb one-half rotation clockwise. Remove the bulb changer tool. The bulb should remain in the sewing machine.

, may be the correct replacement for the tool.
Pfaff has many of their sewing machine manuals on their machine support page. The Tiptronic 2030 support is here: http://www.pfaff.com/en-US/Support/272
. The current link to the manual is http://www.pfaff.com/SiteMedia/PFAFF/Products/Machines/Support-manuals/Tiptronic_2030_2040-manual-EN.pdf?ext=.pdf
. See page 139 (132 of the PDF) for the directions to change the bulb.
I hope this helps.
