Frequently Asked Questions
Does it replace any C5W?
Yes, provided the lamp holder is SV8.5-8 and the required length is 36 mm . C5W lamp holders are available in other lengths (31/39/41 mm); please check before purchasing.
Does it give a burnt-out bulb error (CANBUS)?
In some vehicles, a CANBUS Control Unit (resistor/canceller) may be necessary to prevent error messages. This depends on the car's diagnostic system.
Is it legal to use it in public?
LEDriving Retrofit for C5W vehicles is typically intended for interior use and may not be ECE approved for exterior road use. Please check applicable regulations and your vehicle's manual.
What if it doesn't turn on when you assemble it?
LEDs are polarized components: remove and rotate the lamp 180° in the lamp holder.
