What LED bulbs fit a Modernize Your SL R107 C107 (1972-1989)?

A Modernize Your SL R107 C107 (1972-1989) 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 418 Modernize Your SL R107 C107 (1972-1989) kits covering 1972–2024, each supplied with the correct adapters so no separate bulbs are needed.

Does a Modernize Your SL R107 C107 (1972-1989) need CANbus error-free LEDs?

Most Modernize Your SL R107 C107 (1972-1989) 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 Modernize Your SL R107 C107 (1972-1989) 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 Modernize Your SL R107 C107 (1972-1989) interior LEDs cause flickering?

Not with an error-free kit. Flickering on a Modernize Your SL R107 C107 (1972-1989) 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 Modernize Your SL R107 C107 (1972-1989)?

White (6000K) matches the factory LED signature on late-model Modernize Your SL R107 C107 (1972-1989) 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.

How Do You Install LED Interior Lights in a Modernize Your SL R107 C107 (1972-1989)?

One thing the R107 guys will tell you - turn the lights OFF before you start.

What Should You Know About Keep It Original Where It Counts?
