Description
Overview:
The Sidelight Bulb 12v 4w BA9s (MPN LLB233) is a compact incandescent lamp for 12-volt vehicle lighting circuits. Built with a clear glass envelope and a metal miniature bayonet cap (BA9s/MCC, approx. 8.5 mm diameter), it delivers steady, reliable light for sidelights and instrument clusters. The 4-watt filament produces a clean, warm white output that is easy to see without glare, helping drivers and operators keep key indicators visible. Suitable for cars, vans, light commercials, trailers, plant machinery and garden equipment with 12 V systems, it fits standard BA9s holders with a simple push-and-twist action. Referenced as 233 in many catalogues, this practical bulb is a good choice for replacing worn or dim panel lamps and side/parking lights where a non-LED solution is preferred.
