M-TECH offers several ballast units, both universal to convert halogen installation to xenon, but also substitutes for OEM products (available ballasts have specified range of use in particular car models). We divide the universal ballasts into two groups - the first group includes units for simple cars without CANBUS system, while the second group includes technologically advanced models for cars with burnt out bulb detection function. Individual models are available in standard and slim versions, in case of limited space under the hood. The offer includes ballasts compatible with 12V and 24V installation.
