Review on LASFIT Switchback Polarity Extremely Daytime by Shawn Bass

I purchased this item to complete a complete replacement (indoor/outdoor) with LEDs from 20th century incandescent and halogen lighting. Even if the plastic case doesn't come close to OEM thickness/quality, it's still good a few months after the rebuild. The clear, unpatterned lens allows the Switchback DRL/Park/Turn (Yellow/White) LEDs to shine and project brightly utilizing the molded light diffusion design. Despite the age of my car, the old lighting has been brought into the 21st century with great brightness and intensity. No problems with electrical AM or FM interference during turn signal/alarm operation. In anticipation of unexpected failures I'm happy with the visual/safety improvements as the previous version shown in the picture (no chip) had weird yellow/white combination results regardless of lamp polarity switching. Also see the 12 second video in action. Hope that helps! * Will be returned if durability improvement is still allowed within 1 year. Full Disclosure: I will apply Wipe New to all closed clear outer cases to compensate for the inevitable yellowing of clear lenses over time. due to prolonged exposure to UV radiation. A NOTICE. A replacement relay was installed/required to control the "rapid flicker syndrome" common to older automotive LED applications.
