Overview

CK-wired LED replacement bulbs can fit SRCK- and SACK-compatible vehicle tail lights, brake lights, reverse lights, turn signals or side marker lights. This 3157 dual-contact, dual-function bulb has 18 LEDs (5050 SMD) that create a 360° viewing angle for better, allover light emission with reduced hot spots. Tower-style design with a 16-mm wedge base for easy plug-and-play installation. The energy-efficient bulb operates within a wide 9-14.8V DC range and is designed to last 30,000 hours on your car, truck, SUV, or van—25 times longer than incandescent bulbs. CK bulbs contain both grounds on the same side of the wedge. Use a ground tester or contact your dealer to see if your vehicle has CK light sockets. Available in amber and red. Not sold in pairs. Price per bulb.

Important Notes - Please read before purchasing:
Notes
  1. Your vehicle may require an LED compatible Flasher or Load Resistor. LED brake/tail lamps will not flash with most stock flasher units due to their extremely low current draw. Try our Vehicle LED Bulb Finder to find a compatible flasher for your vehicle. Please See More LED Car Bulb Notes
  2. Oversize
  3. For best results the LED color should be the same as the lens color. If bulb is behind a clear lens, use the appropriate color for turn and brake light functions. Please See More LED Car Bulb Notes
  4. If your daytime running light application serves multiple purposes, this bulb will most likely not work for your vehicle.

Single VS Dual VS CK Dual Filament
Single Filament, Dual Filament, and CK Dual Filament
  • When looking for a replacement bulb, the way the socket is wired determines the part number of the replacement bulb. Sockets that are used for a single intensity call for 3156 or 7440 bulbs (single filament), while sockets that have a dual intensity call for 3157 or 7443 bulbs (dual filament). Dual filament bulbs will function properly in a single intensity socket. So a 3157 bulb will work in a 3156 socket and a 7443 will work in a 7440 socket. However, single filament bulbs will not function in a dual intensity socket. CK indicates where the socket's positive and negative terminals are located. CK LED bulbs are very versatile and can be used in any application a CK or non-CK bulb is used.

THE lamp for Polaris RZR

These lamps are THE plug-and-play solution for the 2012/13/14 Polaris RZR tail lamps. They are brighter than stock at both brightness levels. Couldn't be more pleased with them.

Tried others from other vendors, and they wither didn't work, or didn't work AND blew fuses. These are the ones... don't waste time or money on others.

Great Lights

The LEDs work great. They were purchased to replace the rear taillight bulbs in my Polaris RZR that would get way to hot. These new LED have no heat.

Great Light at a great price

Maybe I did not read into these LED lights enough or what the lowest brightness value must be for a vehicle brake light. But I do not recommend this for your Daily Driver brake light. I did not feel that these are bright enough that other motorist can clearly see you are braking.

Bright when bright, bright when dim

I bought these in red, for use in the brake lights in my Chevy Trailblazer. It takes CK bulbs, four of them.
Dual mode bulbs have a "dim" mode and a "bright" mode. In bright mode, these are SUPER bright. Brighter than even factory incandescents. They look real nice. Unfortunately, "dim" more is also super bright. The difference between brakes no and no brakes on is too subtle. It looks like you're driving around with your brake lights on all the time. It's a shame too because usually the problem with LED bulbs is that they aren't bright enough. If only you could dial back the brightness of the dim mode, these would be great. They are rated 30lm dim, 110lm bright. That seems very unlikely given how little difference there is between the two modes. Nice as these lights are, I wouldn't buy them again given the too-bright-dim-mode.

Response from Super Bright LEDs:

1157 LED bulbs are designed so that one contact operates the less bright tail light and the other contact operates he turn and stop light portion which is brighter. If the socket wiring is reversed, the brighter turn signal will be on when the tail light are on and less bright tail light will be then operated by the turn signal circuit and therefore, not be as visible. Since the 1157 is only able to be installed one way, the only solution is to switch the wires that control the tail and turn signal.

ATV Power Saver

These led tail lights will help when taxing out the electrical system on my Polaris Sportsman when plowing snow and using the winch, lights, hand warmers, every watt counts.
