Brake light EV 400 S
Can anybody tell me If the brake lights also have to light up on the tailgate?? Model ev 400 s. Same question for the direction indicators? Kind regards

We took our 2020 I-Pace to the dealer because the tail lights do not light up when braking. We tried one of the showroom cars and they did light up. We took the car today for repair of the lights and they just told us that some models light up and some don't. I think that is insanity. Why would you want a car to be less safe? They said they were going to have their engineering team try to figure out a way to make them work.

suggestions for dealer: check fuses and check brake light switch are the typical things to do.
The car does not meet federal safety standards if they don't light up. "some don't" is pure BS.

Thanks for the reply. They showed us a dealer's manual which showed that the SE model tail lights illuminate but the S model (ours) don't which is consistent with the earlier post. Nonetheless I agree with you that this is a safety hazard as the existing outside brakelights are only 5 inches long and are hard to see in the daytime. I'm going to continue to push them to fix this as I really feel this makes us more likely to be rear-ended especially when you take your foot off the accelerator and the car slows down so fast.

So you're saying that the brake lights DO work as intended, you would just prefer it if the tail lights (not brake lights) also lit up so it was more visible during the day.

That's very different to the brake lights not working, which I think is what @Ayepace (and I) originally understood.

I don't know if there's any regulation regarding how big the brake lights should be, but I'd bet the i-Pace adheres to it.

Carol, doesn't your car have the high level brake light above the rear widow ( concealed under the roof spoiler ) ?

Cheers, Steve

There are photometry standards. Here's the table from the FMVSS 571.108.

S7.3.13.1 Each stop lamp must be designed to conform to the photometry requirements of Table IX, when tested according to the procedure of S14.2.1, for the number of lamp compartments or individual lamps and the type of vehicle it is installed on.

Table IX: Stop Lamp Photometry Requirements

Maximum Photometric Intensity(4)300360420
(1) The measured values at each test point must not be less than 60% of the minimum value.
(2) The photometric intensity values between test points must not be less than the lower specified minimum value of the two closest adjacent test points on a horizontal or vertical line.
(3) The maximum photometric intensity must not occur over any area larger than that generated by a 0.5° radius within a solid angle defined by the test point range.
(4) Where stop lamps are mounted with their axis of reference less than 750 mm above the road surface, photometry requirements below 5° down may be met at 5° down rather than at the specified required downward angle.
(5) When a taillamp is combined with a stop lamp and the maximum luminous intensity of the taillamp is located below horizontal and within an area generated by a 0.5° radius around a test point (1.0° radius on lamps installed on a vehicle 2032 mm or more in overall width), the ratio for the test point may be computed by using the lowest value of the taillamp luminous intensity within the generated area.
(6) Values followed by a slash (/) apply only to lamps installed on multipurpose passenger vehicles, trucks, trailers, and buses of 2032 mm or more in overall width.

For more information reference 49 CFR § 571.108 - Standard No. 108; Lamps, reflective devices, and associated equipment.
