Which P27/7W 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).

Frequently asked questions
What is a P27/7W bulb?
The P27/7W is a 27/7 W, 12 V automotive bulb with a W2.5x16q base. It’s also sold as 3157.
Is the P27/7W the same as the H6W?
No. Even if they look alike, each size has a different base (W2.5x16q on the P27/7W) and won’t fit another size’s socket. Always buy the exact size your car takes.
Can I replace a P27/7W 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).
