Our HID systems are what we believe to be the easiest system to install.This is because they do not require seperate replay systems or wiring harnessers to connect to the battery.There is no wire cutting involved when fitting these and all connectors are colour coded and fitted with fool proof connectors.This ensures that tey can only be connected the correct way.Full installation instructions are included.If in any doubt,however we do suggest you get an auto electronician to install them.
