Why Switch to LED?
LED bulbs use significantly less energy than traditional incandescent festoon bulbs, run cooler, and last far longer — reducing the need for frequent replacements. The U.S. Department of Energy notes that LED lighting products use up to 75% less energy than incandescent bulbs. Learn more at Energy.gov — Lighting Choices.
Frequently Asked Questions
Q: Will these CANBUS LED festoon bulbs work in my European vehicle without triggering an error?
A: Yes — these C5W/C10W LED bulbs are specifically engineered to be CANBUS error-free. The built-in load resistors communicate correctly with your vehicle's onboard system, preventing the "bulb failure" warning messages common in BMW, Mercedes, Audi, Volkswagen, Volvo, and other CANBUS-equipped cars.
Q: Which size festoon bulb do I need — 31mm, 36mm, 39mm, or 42mm?
A: Refer to your vehicle's owner manual or check the existing bulb's length (measured tip to tip). This 10-pack value set is available in all four festoon sizes. Common sizes: 31mm and 36mm are widely used in dome and map lights, while 39mm and 42mm appear frequently in European vehicles for license plate and interior lights.
Q: How bright are these LED festoon bulbs compared to standard incandescent bulbs?
A: Each bulb outputs 2,400 lumens with a 6000K cool white color temperature — noticeably brighter and whiter than stock incandescent festoon bulbs, while drawing only 2 watts per bulb and generating far less heat.
Q: What is included in the package?
A: You will receive 10 x C5W/C10W LED festoon bulbs in your chosen size (31mm, 36mm, 39mm, or 42mm). No additional hardware or tools are required for installation.
