The odometer light for a 1998 Astra is typically connected to the instrument cluster fuse. In many models, this is fuse number 7, but it's advisable to check the owner's manual or the fuse box cover for the exact fuse designation, as it may vary by model and region. If the odometer light is not functioning, inspecting this fuse for any signs of damage or failure would be a good first step.
Typically, there is no specific fuse solely for the odometer light. Instead, the odometer light is usually part of the instrument cluster, which is powered by a fuse that controls multiple dashboard lights. If the odometer light is not functioning, it may be due to a blown fuse affecting the entire cluster or a malfunction in the instrument panel itself. Checking the vehicle’s owner manual can provide guidance on the relevant fuses.

The fuse panel on a Vauxhall Astra X Reg is on the driver's side, under the dash. Each numbered fuse goes with a specific function.
Odometer Fuse Box RelationshipThat depends on the type of odometer. For example, a mechanical odometer which is driven by a mechanical cable will NOT have any connection to the fuse box OTHER than for lighting, IF the odometer has a light inside of it.On the other hand, if the odometer is of the digital electronic type, it will, in a remote manner, be connected to a fuse which is usually a fuse designated for the "Instrument Panel." In this case, the digital odometer is usually built into/on the Instrument Panel Printed Circuit Board [PCB], and thus will be connected to the fuse box via the PCB wiring harness.

If there is just one light out, the bulb probably burnt out and needs to be replaced. A single bulb will not have a fuse.
