Huge improvement in visibility over the stock bulbs that came with my 2018 Rav4, where driving in the mountains after sunset I could hardly see the road in front of me. With these LEDs, it's an amazing and wonderful difference. It's like exchanging candles for flood lights. They were easy to install for this lady; no professional, husband, or brother-in-law needed. I am extremely happy with the performance of these lights. I am looking forward to my next drive now instead of fearing it.
