What LED bulbs fit a C4 Aircross (2012-2017)?

A C4 Aircross (2012-2017) uses T10 wedge bulbs (W5W/194/168) for the map, door, footwell and license plate lights, and festoon bulbs for the dome and trunk. AutoKitShop stocks 58 C4 Aircross (2012-2017) kits covering 1991–2023, each supplied with the correct adapters so no separate bulbs are needed.

Does a C4 Aircross (2012-2017) need CANbus error-free LEDs?

Most C4 Aircross (2012-2017) vehicles built after 2005 monitor the interior lighting circuit and will show a bulb-failure warning with a plain LED. A CANbus error-free kit includes the resistor or decoder that mimics the original load, so the warning stays off. Older vehicles with a simple on/off circuit run fine on standard LEDs.

How long does it take to install C4 Aircross (2012-2017) interior LED lights?

Allow 15 to 30 minutes. Switch the light off, pry the lens off with a plastic trim tool, pull the old bulb, push in the LED and test it before refitting the lens. If a bulb does not light, rotate it 180 degrees — LEDs are polarity sensitive. No wiring, coding or tools beyond a trim tool are required.

Will C4 Aircross (2012-2017) interior LEDs cause flickering?

Not with an error-free kit. Flickering on a C4 Aircross (2012-2017) is normally caused by the body control module pulsing the circuit to test for a failed bulb. The built-in load resistor in an error-free kit absorbs that pulse. If you already own a non-CANbus kit, adding a decoder resolves it.

What colour temperature is best for a C4 Aircross (2012-2017)?

White (6000K) matches the factory LED signature on late-model C4 Aircross (2012-2017) cars and looks the most OEM. Warm white (3000K) suits older cabins with filament-era trim. Ice blue and purple are aesthetic choices. Colour is selected per bulb, so you can keep the dome white and tint the footwells.

Citroen C4 Aircross (2012-2017) LED Interior Conversion: Light Up the Forgotten Crossover

June 21, 2026

The Citroen C4 Aircross is one of those crossovers that flew under the radar. It's comfortable, well-riding, and shares bones with the Mitsubishi ASX but brings French design flair. One thing it inherited from both parents? Terrible factory interior lighting. The dome light is dim enough that you second-guess whether it's actually on, and the cargo area might as well not have a light at all.

The AutoKitShop ZITWO 11-piece LED kit changes that completely. It replaces every halogen in the C4 Aircross cabin with bright, efficient, long-life LEDs. And because it's CANbus-ready, you don't deal with any electrical gremlins.

What Is a C4 Aircross (2012-2017) Interior LED Light Kit?

A C4 Aircross (2012-2017) interior LED light kit is a set of direct-replacement bulbs that swap into the factory dome, map, reading, vanity, trunk, glove-box and footwell sockets without cutting or rewiring. AutoKitShop lists 58 C4 Aircross (2012-2017) LED kits covering model years 1991 to 2023. Kits for this model run from 2-piece to 17-piece sets. Each bulb is rated at 300 lumens and roughly 3x the brightness of the original incandescent lamp, at a fraction of the current draw, with a 50,000-hour service life. Kits are supplied as complete sets with the correct socket adapters, so nothing needs to be ordered separately. If a bulb does not light on first fit, rotate it 180 degrees, because LEDs are polarity sensitive. Colour options are white (6000K), ice blue, warm white (3000K) and purple.

What Is Included in the C4 Aircross (2012-2017) LED Kit?

Eleven bulbs covering all interior positions across the 2012-2017 model years. Front dome uses a 31mm festoon. Map lights use T10 wedge. Sunvisor lights get the correct mini-wedge bulbs. Rear passenger dome light (most trims have one) gets another festoon. Cargo light in the rear gets a festoon upgrade. License plate lights get T10 wedges. Door courtesy lights where equipped are also covered.

What Should You Know About Forgotten Crossover, Big Improvement?

The C4 Aircross is spacious, practical, and surprisingly capable on rough roads. But driving at night with yellow interior lights ruins the experience. After the swap, the blue-white LED light matches the modern feel of the dashboard instrumentation. The cabin feels newer, cleaner, and more upscale. It turns a ten-year-old crossover into something that doesn't feel its age at night.

How Do You Install LED Interior Lights in a C4 Aircross (2012-2017)?

Since the interior is shared with the ASX, the trim clips are Mitsubishi-style-sturdy but tight. The dome light lens pries forward from the front edge. A spring clip holds the festoon; pull straight out. Map light lenses are individual and pry from the outer edge. The cargo light housing on the passenger side rear panel twists counterclockwise. License plate lights require prying the whole housing off-be careful not to crack the paint. Sunvisor mirror covers slide to the side on most trim levels.

Will LED Bulbs Trigger a Warning Light on a C4 Aircross (2012-2017)?

The C4 Aircross uses a CANbus system similar to other Mitsubishi-based platforms from this era. It's not overly sensitive, but it will catch a dead bulb. Our built-in resistors simulate the correct load so no warnings trigger. If you've been holding off on LED upgrades because you're worried about error codes, this kit removes that excuse.

Which Colour Temperature Should You Choose?

Choose from warm white, cool white, ice blue, or purple. The cool white option matches the factory dashboard LEDs nicely. Each bulb is epoxy-potted for vibration and moisture resistance. Full 12-month warranty against failure.
