Product Description

Upgraded LED Front Turn Signal Light-T3 Series 3157

Normal T series LED bulbs are not perfectly compatible with some vehicles or can't work stably on some specific models and caused error code or hyper flash. Lasfit always deeply cares about user experience and has upgraded the T series based on customers' feedback, that is our T3 Series.

Note:

1. These 3157 bulbs are polarity sensitive. If the LED does not light up after inserting, simply remove it, flip it around and reinstall.

2. For some vehicles, although they use 3157 bulbs, they only have 1 function for turn signal lights, so these switchback led bulbs can not work. If the factory turn signal lights on your vehicle only work for turn signal lights, please don`t use switchback bulbs.

They're definitely brighter for smoked taillight lenses. Didn't stop hyperflash on the turn signals so i moved them to my brake and taillights
