Rear Bumper System
Rear Light Clusters
Each rear light cluster is attached to the body by 4 bolts and nuts. Between each rear light
cluster and the body there is a gasket seal. The rear light clusters are subdivided into com-
partments:
1. Direction indicator
2. Brake force light
3. Reverse light
4. Reflector
5. Tail light/brake light
6. Tail light/brake light
7. Side marker light
The bulbs for the for the tail light, brake light, direction indicator and brake force light are all
held in a common bulb holder with a central connector. All of those lights use 21W long-
life bulbs. The reverse light has a separate bulb holder (16W bulb). The lower part of the
rear light cluster contains a reflector.
The tail light function is performed by two of the rear light cluster compartments. The light
is provided by the 21W long-life bulbs in each compartment, which are dimmed to 6 to 7
Watts.
The brake light function is performed by a 21W long-life bulb in the outer compartment of
each rear light cluster. For the Brake Force Display system, the inner rear light cluster com-
partment is used as an additional brake light.
The direction indicator function is performed by a 21W long-life bulb. The reverse light
function is performed by a 16W long-life bulb on each side (which is replaced with the
holder).

- Side marker light. The outer partition of the outer compartment of the rear light cluster
has an opening through which the tail light illuminates the rear side marker light.
- Brake Force Display. To improve the reaction of other drivers in a panic stop, the E60
has a Brake Force Display System. If an extreme deceleration rate or ABS signal is
detected, the bulbs will receive the full 21 Watts of power and the brake light plus Brake
Force Display function is illuminated.
