This item is sold as a Pair (2 LED bulbs included)
A new even brighter COB design. Very bright Red band of light all the way around the LED, plus a bright tip, all wrapped around of an Aluminum Heat Sink Body. These are very bright 15w LEDs. A 3157 is a common size snap in tail and front corner lights. Uses Epistar brand LED chips.
Use Red under Red when possible for a richer, brighter light. LED Tail lights come on faster, use less power, generate very little heat, and are brighter.
This works with Standard 3157 Sockets. Does not work with 3157CK sockets. See the images on the difference so you can test the socket.
This is a non-canbus light. Canbus is required on some vehicles if the vehicle computer checks for burned out bulbs, or for turn signals (may cause signal to blink rapidly). Trailer lights do not require Canbus LEDs.
A very bright replacement tail light for trailers or vehicles with Towing Heavy Duty Relays. On vehicles without, it will blink rapidly as if a bulb is out. If you don't know if you have a heavy duty relay, remove one bulb and turn on your turn signal. If the indicator and remaining bulbs blink at the normal rate, you can use this bulb as is, but if it blinks rapidly this is not compatible. A Load Resistor can also be put in the circuit to cure rapid blink problems.

replaced the 3157 bulbs in my 2017 f-150 when one of functions in a bulb burned out. These LED versions are far superior to the old bulbs. Brighter tail lights, brighter turn signals and brake lights. Excellent value for the price M4 Note: Please read the product description regarding Canbus and LEDs. It is great these worked in the F350, but note that many computer monitored vehicles will have issue with LED. RVs and Trailers are typically fine with LED.
We replaced our standard park/stop light bulbs with these LED bulbs and the difference they are amazing! great buy and priced right. M4 Products is great to work with and will purchase more from them.
