  • 2020 F550 front marker/blinker
Perfect fit and definitely brighter than OEM. Just installed tonight I’m hoping they last a long time.

  • I liked them enough to order them.
Well, I'm sure I would have liked them, but Amazon fumbled the shipment and it was cancelled/refunded. Not much of a review, but I thought I liked them enough to order them.

  • Read this before buying
I put these in a new 2025 Ford maverick. They failed 9 months later before the truck ever got its first oil change. Not even 5000 miles. Lasfit is sending me another set, but for what? They will fail again within a year, so i will try and find something better. A led should not fail this fast. They are overpriced junk and a LED light should outlast this truck. Buyer beware, they will fail quick! ... show more
