В российском варианте ГОСТа очень мутно написано про режим работы огней и их включения, а также не ясно нужно ли ставить дополнительную кнопку для их отключения, в итоге я привожу оригинальный текст из европейского правила ЕЭК ООН № 48, где об этом не сказано ни слова, опять наши какую то хрень придумали
6.19. DAYTIME RUNNING LAMP (Regulation No. 87)
6.19.1. Presence
Mandatory on motor vehicles. Prohibited on trailers.
6.19.2. Number
Two.
6.19.3. Arrangement
No special requirement.
6.19.4. Position
6.19.4.1. In width: the distance between the inner edges of the apparent surfaces in the direction of the reference axes shall not be less than 600 mm.
This distance may be reduced to 400 mm where the overall width of the vehicle is less than 1,300 mm.
6.19.4.2. In height: above the ground not less than 250 mm nor more than 1,500 mm.
6.19.4.3. In length: at the front of the vehicle. This requirement shall be deemed to be satisfied if the light emitted does not cause discomfort to the driver either directly, or indirectly through the devices for indirect vision and/or other reflecting surfaces of the vehicle.
6.19.5. Geometric visibility
Horizontal: outwards 20° and inwards 20°.
Vertical: upwards 10° and downwards 10°.
6.19.6. Orientation
Towards the front.
6.19.7. Electrical connections
6.19.7.1. The daytime running lamps shall be switched ON automatically when the device which starts and/or stops the engine is in a position which makes it possible for the engine to operate. However, daytime running lamps may remain OFF while the automatic transmission control is in the park or neutral position, while the parking brake is applied or after the propulsion system is activated but the vehicle was not set in motion for the first time.
The daytime running lamps shall switch OFF automatically when the front fog lamps or headlamps are switched ON, except when the latter are used to give intermittent luminous warnings at short intervals. /
Furthermore, the lamps referred to in paragraph 5.11. are not switched ON when the daytime running lamps are switched ON.
6.19.7.2. If the distance between the front direction-indicator lamp and the daytime running lamp is equal or less than 40 mm, the electrical connections of the daytime running lamp on the relevant side of the vehicle may be such that either:
(a) It is switched OFF; or
(b) Its luminous intensity is reduced during the entire period (both ON and OFF cycle) of activation of a front direction-indicator lamp.
6.19.7.3. If a direction-indicator lamp is reciprocally incorporated with a daytime running lamp, the electrical connections of the daytime running lamp on the relevant side of the vehicle shall be such that the daytime running lamp is switched OFF during the entire period (both ON and OFF cycle) of activation of the direction-indicator lamp.
6.19.8. Tell-tale
Closed-circuit tell-tale optional.
6.19.9. Other prescriptions
No prescription.
