A simple cheap upgrade to interior lights. Much whiter than original 578 interior bulbs. Brighter too but not a ridiculous amount brighter. If the bulb doesn’t work when fist put into clips… Reverse the bulb to match polarity and it should work. I thought I had two bulbs that didn’t work but all I did was flip it around and it worked. Hopefully they will last. The original bulbs were very hot when removing them. These are totally cool. I would recommend them as a simple upgrade.
Great product. Would buy again. Did not flicker and shut off when needed. I really like the blue.
Five Stars So much nicer that the regular dome lights. No yellow tint. They fit my 2015 patriot perfectly.
