There’s not much left to upgrade in a BMW since it’s already such a luxurious car, but if you wanted to upgrade some lights, you probably want something up to standard. A quick an easy upgrade for the BMW is to upgrade the turn signal lights. A good choice is the BMW LED turn signal bulbs that have a gorgeous amber yellow output and would be a great addition for the luxury car.
This is a close-up of a 2013 BMW 328i to accentuate the amber color of the turn signal lights. It’s important to have high end turn signal lights because you need to let all the other drivers on the road know exactly which lane you are planning on turning to. If you wanted an easy addition that packs a whole lot of punch, then the LED Turn Signal for BMW F30 3 Series will definitely do the trick.
