I have a 2020 Wrangler JL and swapped out the original halogen bulbs for these H13 led. Absolutely love them! I may have to adjust beam, they appear to cross and converge in the center of the lane. Instructions need some work. Is the heat sink necessary for my application and the bulb only goes in one way can it be adjusted for a straight up/down alighnment? And a tip! First tuck the led driver in before putting bulb in place.
