What the AI looks for in Automobile Special Light Bulbs

Base type and size: Identify the base: wedge (194/168/W5W), festoon (measured by length, e.g. 31mm, 36mm, 39mm, 41mm), bayonet (BA9s) or twist-lock cluster (PC74/PC194). Specialty interior and indicator bulbs look similar but differ in length and base, and festoons must span the clips exactly.
LED polarity: If an LED wedge or festoon does not light, rotate or flip it 180 degrees before assuming it is faulty. Many LED miniatures are polarized, unlike incandescents.
Dimmer and ghost-glow behavior: For instrument clusters and dimmable dome lights, choose LEDs stated as dimmer-compatible. Residual current can make LEDs glow faintly when off or flicker when dimmed.
Color temperature for interiors: Pick warm or neutral white for cabin and map lights rather than very blue cool white. Blue-white light glares at night and reads poorly on maps and in footwells.

Festoon LEDs that are noticeably longer or wider than the original and will not fit the housing.
Very high-output LEDs in small plastic dome housings without heat clearance.

Measure the total length tip to tip in millimeters and match it, as festoons are sold by length.
