Overview

CK-wired LED replacement bulbs can fit SRCK- and SACK-compatible RV tail lights, brake lights, reverse lights, turn signals, or side marker lights. This dual-contact, dual-function 7443 bulb emits 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 9-14.8 VDC range and is designed to last 25 times longer than incandescent bulbs on your motorhome. 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 cool white, natural white, amber, and red. Not sold in pairs. Price per bulb.

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.

2002 Mazda Miata NB Brake Lights

Make sure that when you are ordering brake lights for a NB Miata you get this bulb and not the standard 7443. NB Miatas have a CK socket and need this model for them to function properly.

Bulbs work and look great!

Larger base

The base of this bulb was slightly larger than the bulb it replaced. The bayonet style base just barely wedged into the existing socket on my 2015 Silverado. However, the bulb's contacts still connected and the light works. I am somewhat worried that over time the bulb may pop out. But for now, the bulb is bright and functioning.

Eehh...

I thought these would be a lot brighter than my poem, filament brake lights. Instead, it turns out that the oems are much brighter....WTH. I am returning them and ordering one up from these to see if that helps. I live in an area where there are a lot of drivers that like to ride your tail. Maybe the new ones will send the proper message.

Works great!

Bought these as a replacement for the Sylvania Zevo cause I was getting radio interference with them. No interference now and they’re a bit brighter too.

The fit on a 2002 Toyota 4Runner was perfect.
