BULB - INSTRUMENT 12V 2W - BA7S

A replacement 12V 2W instrument bulb with a BA7S bayonet cap from Link International, listed under part number 45-127-2J. It is the small-format globe used behind speedometer, tachometer, gauge and warning-light housings on a wide range of motorcycles.

Suited to riders and workshops restoring dash illumination on older bikes, or simply replacing a globe that has failed and left one instrument dark. Check the cap type and rating on the bulb you are removing before ordering, as instrument clusters use several similar-looking base sizes.

• 12V rating for standard motorcycle electrical systems
• 2W draw, sized for instrument and gauge illumination
• BA7S bayonet cap (7 mm single-contact fitting)
• Direct replacement globe for dash, gauge and warning-light housings
• Link International part number 45-127-2J

Switch the ignition off, and disconnect the battery where instrument wiring is exposed, before replacing a globe.
Fit by pushing the bayonet cap into the holder and turning about a quarter turn until it locates; do not force or twist the glass.
Handle the bulb by its metal cap and keep fingers off the glass; wipe with a clean, dry, lint-free cloth if you do touch it.
Replace like-for-like at 12V 2W only — a higher-wattage globe can distort or melt the lens and holder and overload the instrument circuit.
Inspect the socket for corrosion or green tarnish and clean the contacts before fitting the new bulb.
Refit gauge seals, gaskets and rubber holders correctly so moisture and dust stay out of the cluster.
If several globes in a cluster are of similar age, replace them together for even, matched illumination.
If a new bulb does not light, check the fuse, the dash dimmer or rheostat and the earth connection before fitting further bulbs.
Store spares in their packaging, dry and away from impact and vibration.
