HELLA EuroLED 75 Red/White 12 V connections

This entry is EuroLED 75 part 2JA 015 247-011: a 12 V red/white downlight with a white plastic screw-mount rim. HELLA's product family page distinguishes the mounting and colour variants. The 12 V and 24 V lamps are separate versions; this part is not a universal 12/24 V lamp.

The instruction sheet, page 1, assigns black to common negative, white to positive for white light, and red to positive for red light. Provide separate switched feeds for colour selection. Red is therefore not the sole positive supply, and the two positives must not simply be bridged together to make a two-wire example. The page remains an overview so its topology preserves that distinction.

The wiring table assigns 3 W to white and 1 W to red. The catalog models those modes separately as calculated 0.25 A and approximately 0.083 A at 12 V. The sheet also quotes 0.19 A alongside its 3 W family specification; that inconsistency is why the conservative power-derived value is identified as a calculation rather than a measured current. Simultaneous operation of both colour feeds is not modelled.

The lamp must be protected by a fuse no greater than 3 A. That ceiling does not mean a 3 A running load or a verified 3 A terminal rating. Select actual source protection for the installed wiring and keep it within that maximum.

Follow the screw-mount drawing for the chosen rim and avoid damaging the factory tinned leads. The housing is sealed to the stated IP6K7/IP6K9K rating, but cable joints still need proper environmental protection and support. Use a compatible PWM dimmer if dimming is required. Do not open the lamp: there are no user-serviceable internal parts.

Test each colour independently with the other positive feed isolated, confirm the selector's off position, and inspect the negative return and protected joints. Confirm that the lamp label is the 12 V part and that the fuse remains within the 3 A maximum. Secure all cables before fitting the trim.
