What LED bulbs fit a AutoKitShop 10-Piece?

A AutoKitShop 10-Piece 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 23 AutoKitShop 10-Piece kits covering 1996–2019, each supplied with the correct adapters so no separate bulbs are needed.

Does a AutoKitShop 10-Piece need CANbus error-free LEDs?

Most AutoKitShop 10-Piece 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 AutoKitShop 10-Piece 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 AutoKitShop 10-Piece interior LEDs cause flickering?

Not with an error-free kit. Flickering on a AutoKitShop 10-Piece 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 AutoKitShop 10-Piece?

White (6000K) matches the factory LED signature on late-model AutoKitShop 10-Piece 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.

AutoKitShop 10-Piece LED Interior Kit for Mercedes Vito W638 (1996-2003) - The Workhorse Gets a Glow-Up

June 21, 2026

Vehicle: Mercedes-Benz Vito W638 (1996-2003)
Kit: AutoKitShop 10-Piece LED Interior Light Kit

The W638 Vito is the definition of a work van that refuses to die. Delivery fleets, trades, camper builds -- these things are everywhere in Europe. But open the door at night and you are greeted by the same dim halogen glow that MB installed in 1996. Time for a change.

I have been following the Vito forum threads on LED conversions for a while. Most guys were piecing together individual bulbs from different sellers. This AutoKitShop 10-piece is the first complete kit I have tested that covers every socket in the van without needing extras.

What Is a AutoKitShop 10-Piece Interior LED Light Kit?

A AutoKitShop 10-Piece 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. (chassis codes W639, W638, W447, C117) AutoKitShop lists 23 AutoKitShop 10-Piece LED kits covering model years 1996 to 2019. Kits for this model run from 2-piece to 23-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.

How Do You Install LED Interior Lights in a AutoKitShop 10-Piece?

The cargo area light is the big win here. Stock, the W638 cargo bulb is almost useless. Swapping to the 300-lumen LED makes finding tools in the back actually possible without a headlamp.

The dome and map lights use festoon connectors. Just pry the lens off with the included tool, pull the old bulb, push in the new one. If it does not light, flip it 180 degrees. Vito dome housings can be tight -- make sure the metal clips are pinched close enough for a solid connection.

License plate lights on these vans are usually seized with corrosion. A little penetrating oil on the lens tabs helps. Take your time with the plastic trim.
