A lamp for automotive front lighting and a vehicle headlight comprising the lamp are described, as well as a method of manufacturing the lamp. The lamp 10 comprises a base 12 for mechanical and electrical connection to an automotive headlight 50. A burner 14 is fixed to the base 12 and comprises an enclosed transparent vessel 22. A first filament 34 is arranged within the vessel 22. A holding wire 30c is arranged within the vessel, and a baffle 40 is arranged proximate to the first filament 34 to partially shield light emitted from the first filament 34. The baffle 40 is fixed to the holding wire 30c. The transparent vessel 22 comprises a vessel wall including a cylindrical portion 24 surrounding the first filament 34. In order to obtain a lamp which may withstand vibration, the vessel wall comprises, within the cylindrical portion 24, a deformed material portion 38 which contacts the baffle 40 or the holding wire 30c. The deformed material portion 38 is shielded from the first filament 34 by the baffle 40. During manufacture, the first filament 34, the baffle 40 and the holding wire 30c are inserted into the vessel 22, and the vessel wall is deformed to provide the deformed material portion 38.
