Got these Auxito led bulbs to upgrade my Tacoma interior lights. The installation was pretty simple for someone seasoned with working on cars, but a quick YouTube search can help first-timers do the job correctly. The difference was significant, as at night the LEDs are much brighter compared to the OEM halogen bulbs. Not only do the LEDs increase the brightness of your interior, but they also make your car look more premium, as many people complimented the look the white lights give the car's interior. The only negative I would have with this product is that I didn't enough lights to change all the lights that use this product, as I didn't have enough to change the trunk light. That however is a nitpick.
