> It's much less awful than the Mini Clubman, which, like so many new vehicles, have decided to install brake lights and signals IN THE BUMPER. My understanding is there's an EU (?) regulation that taillights must be visible when the trunk/hatch is open; eg, for roadside emergencies where you are broken down but are getting things out of the back, your lights must still be visible.
There's a US reg on the subject: lamps on non-fixed parts of vehicles are considered auxiliary, so any of them must be duplicated on a fixed part of the vehicle.
I don't know about EU regs on the subject, I can't remember seeing lights on the bumper aside from rear fogs.
edit: I think it's allowed in the EU as long as the lights are visible as expected, and interestingly brake lights are not covered, however the bumper workaround is also permitted, per Regulation No 48 § 5.18 (https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CEL...)
5.18. Rear position lamps, rear direction-indicators and rear retro-reflectors, triangular as well as non-triangular, may be installed on movable components only:
5.18.1. If at all fixed positions of the movable components the lamps on the movable components meet all the position, geometric visibility and photometric requirements for those lamps.
5.18.2. In the case where the functions referred to in paragraph 5.18 are obtained by an assembly of two lamps marked ‘D’ (see paragraph 2.16.1), only one of the lamps needs to meet the position, geometric visibility and photometric requirements for those lamps at all fixed positions of the movable components; or
5.18.3. Where additional lamps for the above functions are fitted and are activated, when the movable component is in any fixed open position, provided that these additional lamps satisfy all the position, geometric visibility and photometric requirements applicable to the lamps installed on the movable component.
5.18.4. In the case where the functions referred to in paragraph 5.18 are obtained by an interdependent lamp system either of the following conditions shall apply:
(a) should the complete interdependent lamp system be mounted on the moving component(s), the requirements of paragraph 5.18.1 shall be satisfied. However, additional lamps for the above functions may be activated, when the movable component is in any fixed open position, provided that these additional lamps satisfy all the position, geometric visibility and photometric requirements applicable to the lamps installed on the movable component; or
(b) should the interdependent lamp system be partly mounted on the fixed component and partly mounted on a movable component, the interdependent lamp(s) specified by the Applicant during the device approval procedure shall meet all the position, outwards geometric visibility and photometric requirements for those lamps, at all fixed positions of the movable component(s). The inwards geometric visibility requirement(s) is(are) deemed to be satisfied if this(these) interdependent lamp(s) still conform(s) to the photometric values prescribed in the field of light distribution for the approval of the device, at all fixed positions of the movable component(s).
