Antline 194 LED bulbs and interior lights
Most interior lights use a few tiny bases: 194 / T10 wedges, festoons, BA9S and T5. Antline makes them in bright white and seven colours, most of them CAN-bus error free and close to stock size.

The 194 LED bulb: the most common interior base
The 194 (also 168, 2825, W5W and T10) is a small glass-wedge bulb found in dome lights, map lights, door courtesy lights, trunk lights, side markers and license-plate lamps. A 194 LED bulb with 9 high-power chips is several times brighter than the halogen and stays cool. Because LEDs are polarity-sensitive, a bulb that does not light just needs turning around.
Festoon, BA9S and T5
- Festoon: double-ended bulbs measured tip to tip — 29, 31, 36 or 41 mm.
- BA9S: a tiny bayonet used in gauges, map lights and many European cars.
- T5 / 74: miniature wedges behind dashboard gauges and switches.
Colours like ice blue and red restyle a dash; white is the brightest for reading.
Interior & Dome: questions
What does CAN-bus error free mean?
The bulb includes circuitry so most cars do not show a bulb-out warning.
How do I measure a festoon?
Measure the old bulb from tip to tip in millimetres.
Can I mix colours?
Yes, but keep exterior markers and plate lights in legal colours.
