Which P27W to buy: standard, brighter or long life
- Standard: the classic incandescent bulb; cheap and no dashboard warnings.
- LED: whiter light and lower power draw. On turn signals and brake lights they can cause hyperflash or bulb-out warnings: choose CANbus versions or add load resistors.
- Long life: handy where bulbs are hard to reach (tail lights or dome lights).
To confirm which bulb each light on your car uses, follow the methods in how to find out which bulb your car takes.

Frequently asked questions
What is a P27W bulb?
The P27W is a 27 W, 12 V automotive bulb with a W2.5x16d base. It’s also sold as 3156.
Is the P27W the same as the T4W?
No. Even if they look alike, each size has a different base (W2.5x16d on the P27W) and won’t fit another size’s socket. Always buy the exact size your car takes.
Can I replace a P27W with an LED?
Yes, LEDs are common for turn signals, parking, license plate and dome lights. Pick CANbus versions or use load resistors to avoid hyperflash and bulb-out warnings, and keep the correct color (amber for turn signals, red for brake lights).
