Replacing the Rear Bulb on a Smart Roadster

Model: Smart Smart 454, Fourfour1 - Years 2004-2006
Part: Tail light bulb

Open the rear boot door and remove the circular seal (in the area of the headlamp) located on the body of the boot. Unscrew the T20 Torx screws securing the affected headlamp to the body and extract it. At this point, you can access any bulb that has blown from the rear. You can similarly access the indicator bulb, the stop bulb, or the regular dipped beam. To do this, simply disconnect the connector, unscrew the bulb, and screw in the new one. Proceed in reverse for complete assembly.

How to Adjust the Handbrake on a BMW 1 Series?

Once this cover is removed, you will be able to locate the spring that regulates the handbrake tension. At this point, adjust the nut located at the base of the spring: tightening the nut will make the handbrake firmer and reduce the lever's travel. Conversely, loosening the nut will decrease the handbrake's firmness and increase the lever's travel.
