There is also an upgrade that you can do for older models

I don't have a 707 but do have a 530-2 Record. Unfortunately, with some of these older machines, Bernina did not provide a very good method for accessing the light bulb. On later machines, the side cover would either be hinged or removable. If yours doesn't have this capability, the only way of changing the bulb is by reaching in with your fingertips, gripping, and turning the bulb to remove it and then installing the new bulb in the reverse manner (difficult for someone with big fingers). Sometimes it helps to use thin rubber gloves (like the surgical type), lightly moisten the finger tips to provide more "grip." There is also a sewing tool available that is somewhat like a pencil with a rubber suction at the end made specifically to help with replacing sewing machine bulbs. If you are creative, you may be able to fashion something similar.

Have you tried LED bulbs? I've installed them in all my Berninas. They provide a lot more light and do not get as hot as the regular bulbs--as well as, they supposedly last much longer! They seem expensive at the outset but if I never have to change a bulb again, so much the better!

In case you need it, here is the manual for your machine:

Looks like you bulb is a bayonet style. Push up and rotate the old bulb to remove. Install the new bulb the same way--push up & rotate to lock in place.

Note: there is also a bulb remover tool

You might check out some of the older Bernina manuals to get an idea of how it may work in your machine. The 1260 is the closest manual available. Looks like your machine takes the same push-in bulb. So, you would push up on the bulb and twist. Then you would install the replacement the same way. Sometimes, using tight fitting medical gloves helps grip the bulb in order to twist.

BTW--I have older Berninas and upgraded their bulbs to LED.

How To Change Bulb In Sewing Machine

Hi Rhonda I have a 9000 and a 500e and the light should be directly above the needle shaft.
Good luck

If you still have original Acessories there should have been a grey or brown cone shaped rubber gripper that could be slid up on bulb to assist in turning it If not remove the side cover, then back cover to access the bulb. Some 1008's have push in bulb others screw in so be careful not to break bulb as you remove it
push in bulbs must be pushe in and rotated 45 degrees counter clockwise to remove. Of course screw in bulbs just rotated counter clockwise to remove

My light went out of my Singer advance 7422. Does anyone know how to change it or where to buy the bulb? Thank you for your help.
