The most important thing to consider when choosing the right lumens for your vehicle is the purpose of the light. It's not uncommon for cars to have LED headlights with a higher lumen rating than the taillights. This can cause problems, such as making the car look smaller than it is, and causing issues with braking and following distance. The most common reason for this discrepancy is the way tail lights are designed. They often have a larger light source, which gives the impression of brighter lighting. The taillights should only have enough lumens to meet the minimum requirement.
