Lexus RX 300: Lights and Instruments
Affects Lexus RX 300 · 1999 — about 1K vehicles.
The hazard
On certain vehicles, due to a programming error of the automatic light control system, the headlights and tail lights may not automatically illuminate in low and ambient light when the headlight switch is placed in the "Auto Position". Under this condition, only the daytime running lights are illuminated. In low ambient light, the vehicle would become difficult to see, especially from vehicles behind, since no headlights (low beams) and tail lights are illuminated, increasing the risk of a accident. Correction: Dealers will replace the body ECU
