Excellent Upgrade — Completely Modernized My BMW
I’m extremely happy with these taillights. I installed them on my 2009 BMW 335xi E90, and they completely updated the appearance of the car without making it look overly modified.
The clear-smoke design looks especially good against my Space Gray paint, and the LEDs are bright, crisp, and give the rear of the car a much more modern appearance. Fitment was very good and the finished installation looks clean and close to OEM quality.
I wanted something that would modernize my older BMW while still keeping it classy, and these accomplished exactly that. They made a much bigger difference to the overall appearance than I expected.
Very pleased with the quality, fit and appearance. I would definitely recommend them to other E90 owners looking for a tasteful lighting upgrade.
