What LED bulbs fit a Test Article?

A Test Article 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 0 Test Article kits covering the full model run, each supplied with the correct adapters so no separate bulbs are needed.

Does a Test Article need CANbus error-free LEDs?

Most Test Article 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 Test Article 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 Test Article interior LEDs cause flickering?

Not with an error-free kit. Flickering on a Test Article 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 Test Article?

White (6000K) matches the factory LED signature on late-model Test Article 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.

What Is a Test Article Interior LED Light Kit?

A Test Article 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 0 Test Article LED kits covering model years the model run. 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.
