C5W 36mm Car LED Bulb

C5W 36mm LED festoon (SV8.5): fresh or cosy light for interior and number plate

C5W is a tubular bulb with a metal cap at each end, also called festoon or SV8.5. The 36 mm version is often used in interior and reading lights, the boot, the entry lighting or the number plate light. Here you will find C5W 36mm LED bulbs 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 heatsink. All bulbs are supplied in sets of 2.

What to look for when choosing

• Length: C5W comes in several lengths. This collection is for 36 mm; for 31, 39 or 41 mm, choose another collection.
• Light colour: warm white gives a cosy light, daylight white a fresh, bright light.
• Technology: filament bulbs resemble the original tubular bulb in shape; with SMD and COB the LEDs sit on a small board.
• Voltage: 12V for passenger cars, 24V for trucks and buses.
• CAN-BUS: if your car's on-board computer monitors the bulbs, preferably choose a CAN-BUS version.

Will it fit your car?

Measure the old bulb from cap to cap in millimetres and choose the same length. Also check the thickness: an LED bulb with heatsink is sometimes wider than the original. Do you get a bulb warning, or does the bulb glow faintly when switched off? Then we recommend a CAN-BUS version or a suitable resistor; see our LED resistors.

Laws and regulations

If you use a C5W LED bulb in the number plate light, the light colour and operation must meet the legal requirements. So check in advance whether use in your vehicle is permitted.

Need a different length? Also take a look at the C5W 31mm LED bulbs, the C5W 39mm LED bulbs or the C5W 41mm LED bulbs.
