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 1157 is a common size for push and turn tail light bulbs. 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 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.

I have an RV where the brake light housing isn't very reflective, so I needed an LED bulb that illuminates from the end. This fits the bill and the COB LED provides smooth illumination. Very satisfied!
I have an 05 Monaco which has small tail lights. I installed larger incandescent bulbs (2357) to improve visibility but it only helped a little. I took a chance on these red bulbs from M4 and they work as advertised. Finally brighter tail and brake lights. They are brighter all the way around and facing aft as well. Definitely a good addition to safety. I also purchased a tail light strip but I may decide to put that on the toad instead now.
