Overview

CK-wired LED replacement bulbs can fit SRCK- and SACK-compatible boat and RV applications such as navigation lights, cabin lights, dome lights, tail lights, brake lights, reverse lights, turn signals or side marker lights. This 3157 dual-contact, dual-function bulb has 45 LEDs (3528 SMD) that create a 360° viewing angle for better, allover light emission with reduced hot spots. Produces up to 70 lumens. 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 motorhome or boat—25 times longer than incandescents. 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. 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
  3. If your daytime running light application serves multiple purposes, this bulb will most likely not work for your vehicle.
  4. To protect LEDs in marine applications, it is advisable to use a 12 VDC line conditioner to compensate for voltage irregularities common in marine low-voltage systems.

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.

Works Great

I chose the red LED's with the red tail light lens. I did a comparison with one side LED and one side factory bulb. The LED is slightly brighter than the factory bulb and looks great. The factory bulb was bright enough, but I like the longevity and the cool temperature of the LED.
The LED tail light and LED back-up light are on the left in the picture.

Perfect Plug & Play in my 2013 RZR 570 LE

I want to avoid the melting taillight lens that seems to be an issue - these simply plug in and work!

Great balls of fire!

Yes they are very bright - 50% more so than standard incandescent 3157s. I had to install a resistor (to eliminate hyper-flash), but this was no problem for me. These lights are well worth the effort, and they well satisfy my requirement of being visible and making intentions known to fellow drivers.

If I may offer advice on resistor installation to those with less technical experience: you may need to add the resistor ACROSS the flasher circuit. This means between the flasher circuit hot lead and ground. The resistor will get very hot after a minute or two during use - this is normal. DO secure the resistor to a fixed metal surface using screws or rivets. DO NOT affix the resistor to, or in very close proximity to any plastic or rubber components, use tape, or let it hang freely.

Great LED

Put this in my rear tail light housing of my RZR UTV. Bright and easy to put in. Will not have to worry about it going out or melting my housing.

thanks.
