Excelente Calidad de producto , realmente funcionan como luz de día blanca y amarillas cuando activas las direccionales o intermitentes.

These were super easy to install. Just pull out the old ones and pop these back in. Really nice to have extra white light when not using the turn signals. And the turn signals are super bright now. Would definitely get them again.

Works great on my Ford maverick

Recently installed these onto my 2022 Ford Maverick (literally last night) and they are bright! Much better looking than the amber DTRL as they are switch backs, they switch from white to amber (only when turning). So far very pleased with these.If there are any issues, will update.

Only functions as a turn signal on a 2025 Maverick does not have the always on white parking light as it shows

Easy to install. Nice and bright and turn signal is much more visible. Before installing these, it seemed like people sometimes couldn’t tell if I was turning. Haven’t had the issue with these bulbs.
