For the 2017 Acura TLX, both the low-beam and high-beam headlights use LED lighting. The supplied fitment data does not list a replaceable bulb size for either headlight, so confirm the lamp assembly and service requirements before ordering a replacement.
The fog lights, daytime running lights, parking lights, front and rear side markers, tail lights, brake lights, center stop light, license plate lights, dome light, map lights, and door-mirror lights are also listed as LED. No separate halogen bulb size is provided for these applications.
- Front turn signal: 64132
- Rear turn signal: 7440
- Reverse light: 7440
- Glove box: 2721
- Interior light: 158
- Trunk light: 168 or 917
- Vanity light: 6615F
Because the trunk light has two listed bulb options, check the existing bulb or socket before purchasing. This fitment data does not identify additional headlight-type or trim-specific variations.
