C5W 41mm Car LED Bulb

C5W 41mm LED festoon (SV8.5): the long size, from 41 to 43 mm

C5W is a tube bulb with a metal cap on both ends, also known as festoon or SV8.5. The long versions of 41 to 43 mm are often used in interior and ceiling lighting, the cargo area, or the license plate lighting. Here you will find C5W LED bulbs of 41, 42 and 43 mm in daylight white (6000K and 6500K) and warm white (3000K). You can choose from filament, SMD and COB, for 12V or 24V, and there are several CAN-BUS versions, some with a heatsink. All bulbs are supplied in sets of 2.

What to pay attention to when choosing

• Exact length: this collection contains bulbs of 41, 42 and 43 mm. The length is stated in the product name; choose the size that matches your old bulb.
• Light colour: warm white gives an atmospheric light, daylight white gives a fresh and bright light.
• Technology: filament bulbs look like the original tube bulb in shape; with SMD and COB, the LEDs are on a board.
• Voltage: 12V for passenger cars, 24V for trucks and vans.
• CAN-BUS: if the onboard computer of your car checks the bulbs, preferably choose a CAN-BUS version.

Does it fit in your car?

Measure the old bulb from cap to cap in millimeters and choose the same length. Also pay attention to the thickness: an LED bulb with a heatsink is sometimes wider than the original. Do you get a bulb error message or does the bulb continue to glow dimly? Then we recommend a CAN-BUS version or a suitable resistor; for this, check our LED resistors.

Laws and regulations

If you use a C5W LED bulb in the license plate lighting, the light colour and operation must meet the legal requirements. Therefore, check beforehand whether use in your vehicle is permitted.

Need a different length? Also check the C5W 36mm LED bulbs, the C5W 39mm LED bulbs or the T10 LED bulbs.
