The relatively small back light does not actually show the actual width of a BMW, especially when side cases are attached.
This tailor-made 3M film kit reflects the light shining on it which increases the signalling effect considerably. The actual width is immediately visible and the vehicle can be seen from a distance, increasing passive safety enormously.
Simple to apply. Made-to-measure for original BMW cases.
