2018 Audi TT RS bulb fitment uses LED lighting for both the low-beam and high-beam headlights. The supplied fitment data does not identify a separate bulb code or a projector/non-projector variation, so verify the original lamp assembly before ordering a replacement.
LED applications also include the fog lights, front and rear turn signals, reverse lights, brake lights, center stop light, cornering lights, daytime running lights, parking lights, front and rear side markers, tail lights, and license plate lights.
- Interior LED locations: dome, map, and vanity lights.
- 2825 locations: glove box, general interior, and trunk lights.
- Replace only the listed bulb type for the applicable location, and confirm the vehicle’s existing assembly if the lighting equipment has been changed.
