GE 1156 27W 12.8V S8 BA15S Bulb Pair

This two-pack supplies replacement lamps for vehicles using the 1156 single-contact bayonet base. Each unit draws 27 watts at 12.8 volts and fits the standard S8 envelope. They are intended for drivers needing direct-fit automotive lighting.

Steady Output During Extended Operation

The filament is rated for 27 watts continuous draw at 12.8 volts, so brightness remains consistent while the circuit is active. Heat rises predictably in the compact S8 envelope during prolonged use. No thermal throttling or output fade occurs within the design limits.

Verify Base And Voltage Before Ordering

Confirm the socket accepts a BA15S single-contact bayonet and that the vehicle system delivers 12.8 volts nominal. The 1156 designation must match the original equipment specification exactly. Buyers who need a different base type or voltage should select another product.

Questions about this item

How much heat does the 27W 1156 bulb produce during extended use?

The 27W filament generates noticeable warmth when lit for long periods; allow the glass envelope to cool before handling after continuous operation.

Which socket must my vehicle already have for the BA15S base to fit?

Your vehicle needs a single-contact bayonet (BA15S) socket that accepts the 1156 bulb form factor for a secure electrical connection.

Will the 12.8V rating work reliably in a classic 12V electrical system?

Yes, the 12.8V design matches typical charging-system voltage, so it operates normally alongside original wiring and regulators in older vehicles.
