194 is a classic “small bulb” code used on a huge range of vehicles. Common positions include license plate lights, side markers, parking/position lights, and many interior locations like map/dome/glovebox (depending on the car).
Why 194 is a popular LED swap
Easy access in many housings
Instant-on response and crisp appearance
Longer life (with quality bulbs)
Tips for a clean result
Choose bulbs with good side-firing spread for markers and license plate lights.
For interior, don’t overdo brightness – comfort matters.
If the LED doesn’t light, flip it (polarity).
