Compatibility depends on your vehicle model, production year, trim level, and original head unit type. Please check the product compatibility information carefully or contact us with your vehicle details before ordering.
Is professional installation required for CarPlay systems?

Tire Pressure Monitoring Systems (TPMS)
How does TPMS work?
TPMS sensors are installed on the wheel valves and transmit tire pressure data wirelessly to a display unit or the vehicle's instrument cluster, alerting the driver when pressure falls outside the recommended range.
Does TPMS installation require a professional?
Yes. Sensor installation involves deflating the tire and may require tire removal. This work must be performed at a qualified tire service center.
Can TPMS replace regular manual tire pressure checks?
No. TPMS is a supplementary monitoring tool only. Regular manual tire pressure checks following the vehicle manufacturer's specifications remain necessary.
Headlight Parts (Xenon Ballasts & LED Modules)
How do I find the correct ballast or LED module for my vehicle?
Compatibility depends on the part number, connector type, headlight version, and vehicle configuration. Please check the product compatibility information on the product page or contact us with your vehicle details and original part number.
My headlights are not working after installation. What should I do?
Headlight issues may be caused by incorrect part fitment, connector issues, wiring faults, moisture, or other vehicle-related factors. Please contact a qualified automotive technician to diagnose the issue. Do not attempt further adjustments without professional assistance.
Will replacing a ballast or LED module trigger a warning light?
Some vehicles may display warning lights or require a diagnostic reset or coding after replacing lighting components. A qualified technician can perform this reset if required.
Dust Caps
How do I choose the correct dust cap size?
Dust cap fitment is determined by the diameter and shape of the headlight housing opening. Please measure your headlight opening or refer to the product compatibility information before ordering.
My dust cap does not fit properly. What should I do?
Do not force-fit a dust cap that does not match. Please contact us with your vehicle details and headlight information so we can assist you in finding the correct size.
