Review: 2003 Toyota tundra - Nice and bright compared to the stock bulbs on the truck. Very easy to install, simple plug and play. Will see how long they last but so far they are working well.

### ⭐⭐⭐⭐⭐ Very nice especially with no resistor needed
*by R***B on January 2, 2026*

Got these while doing a LED conversation on my 2018 Jeep Grand Cherokee. The install was a pain in the a--, but that was because of the car, not the bulb. Worked like it should, looks great, crisp and bright. Hopefully they last. So far would recommend.
