In brief
Installation is not limited to placing two more lamps.
Useful to know
HELLA offers additional headlights in various constructions and light variants. The choice must take into account the purpose, installation location and electrical control. [1]
Before assembly, separate the questions: where it is fastened, how it is powered and when it is triggered. The decorative similarity does not prove the same light function. For public road use, check the specific product and applicable vehicle and location requirements. No universal permission for adding random lighting is given here; it explains why a technical integration has more than one parameter.
