DRL in the meaning of EU law (from 07.02.2011) means separate, dedicated lamps which cannot be used for anything else then making the car visible
The regs seem to allow DRL's within existing lamps, using a common light source.
Regulation 87 (Uniform Provisions Concerning the Approval of Daytime Running Lamps for Power-Driven Vehicles), under General Specifications, para 6.3 states:
"Daytime running lamps, which are reciprocally incorporated with another function, using a common light source, and designed to operate permanently with an electronic light source control gear to regulate the intensity of the light emitted, are permitted."
For clarity, taken from Reg 48:
"Reciprocally incorporated lamps" means devices having separate light sources or
a single light source operating under different conditions (for example, optical,
mechanical, electrical differences), totally or partially common apparent surfaces
in the direction of the reference axis and a common lamp body.
