2019 Audi TT RS bulb fitment uses LED lighting for both the low-beam and high-beam headlights. The supplied fitment data does not identify separate bulb sizes or a projector versus non-projector headlight variation, so no halogen replacement code is listed for either beam.
The fog lights, front and rear turn signals, daytime running lights, cornering lights, parking lights, side markers, tail lights, brake lights, center stop light, and reverse lights are also listed as LED. Exterior lighting is therefore primarily LED-equipped rather than using conventional replaceable bulb codes.
- Headlights: LED low beam and LED high beam
- Interior: Dome, map, and vanity lights are LED
- 2825 bulbs: Listed for the glove box, interior, and trunk lights
- License plate: LED
For replacement work, verify the existing lamp assembly and connector before ordering, especially where the vehicle uses an integrated LED unit. The 2825 fitment applies only to the listed glove-box, interior, and trunk applications in this data.
