BULB - INDICATOR 12V 23W - BA15S

A replacement indicator globe for motorcycles running a 12 volt, 23 watt BA15S fitting, also known as the 1156 type. It suits riders replacing a blown or dimming turn-signal bulb without changing the existing indicator housing or wiring.

The BA15S base is a single-contact bayonet cap with straight-aligned locating pins, so it drops into any standard BA15S socket with a push-and-twist fitment. Check your bike's globe chart or the old bulb before ordering, as visually similar fittings such as BAU15S use offset pins and will not seat correctly.

• 12V 23W rating for standard motorcycle indicator circuits
• BA15S single-contact bayonet base (1156 type)
• Direct replacement for stock indicator globes using the same fitting
• Sold as a spare or repair part — no wiring changes required

Turn the ignition off and let a recently used bulb cool before removing it.
Remove the indicator lens, then push the bulb in and twist anti-clockwise to release the bayonet base; fit the replacement by pushing in and twisting clockwise until it locks.
Confirm the old bulb's pins are level with each other (BA15S) rather than offset (BAU15S) before fitting, as the offset type will not seat properly.
Handle the globe by its metal base and keep the glass clean and free of grease and fingerprints.
Check the socket contacts for corrosion or moisture and clean them if the globe has been failing early or flickering.
Refit the lens and its seal correctly so water cannot enter the housing.
After fitting, test both left and right indicators — a fast flash rate usually means a bulb is blown or the wattage does not match the circuit.
Store spares in their packaging in a dry place, and avoid dropping or knocking the globe as the filament is fragile.
