Are you allowed to replace a halogen bulb in any headlight with a xenon lamp?

Correct answer
B. No, because it may lead to dazzling other drivers.
Explanation
You must not fit a xenon lamp in a headlight instead of a halogen bulb - answer B, because it may dazzle other drivers. Neither an emergency situation (A) nor a matching cap (C) justifies it.
A headlight is designed for one type of light source: the reflector and the lens are matched to the position and power of the filament. A xenon lamp shines several times brighter and has a different light source, so in a halogen headlight the beam scatters above the boundary between light and shadow (the cut-off line) and dazzles oncoming drivers; this is why factory-fitted xenon lights have automatic height adjustment and washers. The Regulation on the technical conditions of vehicles requires that lights do not dazzle other road users and give a clear boundary between light and shadow, and the Road Traffic Act requires that a vehicle does not endanger the safety of others.
Legal basis: § 13 para. 1 point 4 and 5 of the Regulation on the technical conditions of vehicles and the scope of their necessary equipment; Art. 66 para. 1 point 1 of the Road Traffic Act (Prawo o ruchu drogowym)
