Which R5W 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 R5W bulb?
The R5W is a 5 W, 12 V automotive bulb with a BA15s base. It’s also sold as 207.
Is the R5W the same as the W16W?
No. Even if they look alike, each size has a different base (BA15s on the R5W) and won’t fit another size’s socket. Always buy the exact size your car takes.
Can I replace a R5W 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).
