P21/5W Halogen Car Bulbs are similar to P21W bulbs, but they have a dual filament design that provides both brake light and tail light functionality. When choosing P21/5W bulbs, you should consider the same factors as for P21W bulbs, with the addition of the following:
Filament design: P21/5W bulbs have two filaments - one for the brake light and one for the tail light. It's important to make sure that both filaments are working properly, as a failed filament can result in reduced or non-existent functionality.
