Review: Makes for a great addition that fits in stock interior lighting - I installed this in my fiancé's '06 Dodge Charger dome lights. They fit perfectly. She has them forever set onto purple because it's her favorite color. They're very easy to install, so it made for a fun first car mod for me and her to do together. They've been in for over 6 months and have worked great. They aren't too bright, which is probably because of the dark color that she chose to keep it on, but they've never made it impossible to find something in the car. The incandescent bulbs do a kind of "fade out" effect when you turn the car off. The LEDs do not do this, they just immediately dim to the point of barely visible, and flash like crazy. Not that big of a problem when your turning off your car, and it doesn't bother her at all. If it's something that will bother you, you might want to look into an incandescent with a colored lens.
Review: Great product - These are great!. Just installed them on my 310 Sundancer. Way easier than re-wiring in new lights. Couple points, one is you must use caution installing them. These are a circuit board with Festoon ends, put the pressure on the silver festoon ends not the board. Two, yes they are not as bright at the incandescent bulbs they replaced but it’s negligible. I wish the remote didn’t have to be pointed directly at the bulb to change modes but only an inconvenience if you are trying to use a mode like flash or fade.

### ⭐⭐⭐ Kinda cheap feeling, not very bright. Experience may vary by vehicle.
*by P***E on November 25, 2025*

They're a little buggy and could be brighter. They flicker when they first turn on, probably because my car un dims them to full brightness rather than just turning them on when you open the door. I have other colored leds that don't change color that I'll probably switch back to because they were brighter overall. These seem kinda cheaply made compared to them and those were cheaper than these are.
