These lights are phenomenal. I recently got a 2021 Ford F-250 XL and I am very familiar with LEDs as I like to see at night. As some might know, H13 bulbs are dual-purpose lights, meaning they act as low beams and high beams, and my truck has 4(2 per headlight). These claim 12,000 lumens per bulb, so I'd have 48,000 lumens, and let me tell you... I believe them. Installed them and just went for a drive at night to test them out and holy crap, my low beams are the brightest low beams of any vehicle I've ever been in and I've been in some bright light vehicles. High beams are pretty bright too but the low beams... I don't know if there is a legal limit for lumens or what but if there is in the state of Michigan I'm probably past the limit as I got brighted 8 times on my 30-mile drive.
