New R&D BMW headlight assembly behind the scenes! 🙌 We know how crucial it is to see at night, so we have Caleb here working out the insides & outs of these headlight wiring harnesses for you BMW owners out there! Should come out pretty nice; what else are you curious about that we work on here at ECS? If you drop some recommendations, we’ll try to put some focus on it for ya! #ecs #ecstuning #wiring #bmw #bmwe9x #e9xm3 #m3 #bmwe90 #bmwe92 #bmw335i
