Alla Lighting Super Bright BAU15S 7507 LED Bulbs 39-SMD High Power 2835 Chipsets 12496 1156PY PY21W Red Turn signal Blinker Light Replacement

Replaced the turn signal bulbs (f&r), reverse and brake light bulbs on 2014 BMW longroof which came with standard incandescent signal lights. Review the pictures to see one side w/LED and the other existing bulbs. Used amber to replace the amber front turn bulbs, red to replace the clear rear turn and brake and clear for reverse. Thoughts: The LEDs are brighter, I'd say 30% for the rears and 40% brighter for the fronts, acknowledging that the LEDs are new and the existing are 5 years old so this advantage may not be as big as LEDs get older. Additionally, the LEDs are a full brightness for the entire cycle whereas the standard take time to fully illuminate. Beam pattern is good and works well within the reflectors. The red lights are a more deeper red, hard to describe and show in pictures they look more up new car standards. Can't comment on longevity yet. Caveat: The LEDs required coding for the car not to perform the current test which cause the LED bulbs to flicker every minute. Furthermore these bulbs did not trigger any malfunction errors. Conclusion: The LEDs make the car look more modern, incandescent bulbs indicate a car built long ago. The LEDs are brighter and are at full brightness sooner and longer. A worthy upgrade that took about 2 hours with coding and around $75 total.
