2x Flavel 25W 300°C Oven Lamp Bulbs - E14 Small Edison Screw (SES), 240V For Cookers

Did the light burn out in your Flavel oven?

This is the fix.

You get a pack of two 25-watt oven bulbs that are rated to handle the heat—up to 300 degrees Celsius.

They have the small Edison screw (E14) base, which is common in many cookers.

They run on standard 240V.

Just screw them in and you'll be able to see your casserole without opening the door.

Unbranded, but they're made to fit Flavel ovens and should do the trick.
