These 3157 LED taillight bulbs are an EXTREMELY bright alternative to their incandescent cousins. When using this bulb for your taillights, it is better to select the 3200K as it’s soft yellow light is more compatible with the red lenses on the back of your vehicle. The 4100K has a tendency to wash out the red lenses to a red-orange when the breaks or turn signals are applied.
The RED bulb is best used in taillight lenses that are old and faded. The RED bulb is still a VERY bright bulb ad compliments the purpose of the taillight.
The AMBER bulb is used for the front parking/turn signals.
Unlike the 7443 bulbs, the 3157 has tabs on the base that clicks into the socket. Sometimes you have to put on of the tabs in first (on an angle) and then snap the other side in.
The 33 High Efficiency 5730 LEDs produce pure white light. The 3157 wedge style ensures proper bulb alignment in the tail light assembly. This dual intensity LED bulb lights at 800 lumens when the parking lights are on and puts out a whopping 1600 lumens when the brake lights or turn signals are activated. As bright as a standard 100 watt light bulb!

I had bad experiences with products from other sellers in the past. Cabin Bright bulbs are outstanding and their support is second to none. They have been, and will continue to be my source for LED bulbs. They should be yours too!
