2006 Toyota Mark X Headlights

Headlights are fitted and fully relevant to the 2006 Toyota Mark X (GRX120/121). This is documented in Toyota’s owner’s manual for the GRX120 series and the Toyota Electronic Parts Catalogue, with compliance to ADR 13/00 and UNECE R48 lighting requirements for dipped and main-beam lamps. Depending on grade, the Mark X runs halogen low/high beams or a factory HID (xenon) low beam with auto-levelling and, on some trims, headlamp washers.

On this model, the headlights do the heavy lifting for night visibility and daytime conspicuity. Halogen variants typically use H11 for low beam and HB3 (9005) for high beam. HID-equipped cars use D2S for the low-beam projector and retain HB3 for high beam. Either way, the goal is clear forward light, a crisp cutoff to avoid glare, and reliable operation through all kinds of weather—key for roadworthy checks and WOF/COF inspections.

When fitting halogen bulbs, avoid touching the glass
