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 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 with in a wide 9-14.8 VDC range and is designed to last 25 times longer than incandescent bulbs on your car, truck, SUV, or van. 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.

CAN Bus CAN Bus LED bulbs are simple plug-and- play LED bulbs which are made specifically for CAN Bus-equipped vehicles. These bulbs work with your vehicle's advanced computer system, so when your vehicle's computer reads them, they respond back correctly. To see if your vehicle operates with a CAN Bus system, simply remove the bulb you're looking to replace, start your vehicle, and if you have a "Bulb Out" message on your dash you have a CAN Bus system.	No

They are divided into categories for each product type and certification type to allow for very specific qualifications related to each product. When this system is being used as intended, it gives consumers, installers, suppliers, and anyone else that may be involved confidence that the product is safe and will work well in their application. The most common UL and ETL certifications relate to safety and installation, although they do also provide some sanitation-related certifications (using NSF standards). Another common certification body is the DLC, which specializes in certifying the performance of a light—mainly related to environmental impact and electrical efficiency.

Comparing Lumens Across Colors: Why Do Colored Bulbs Have Such Low Lumen Values

Lumen meters are a great way to measure white light output but can be deceptive for colored bulb intensity. Lumens measure light wavelengths in all colors of the visible spectrum. Because multiple wavelengths create white light and colored bulbs are a single-wavelength source, colored bulbs will have lower lumen readings. However, they will appear equally as bright as a white bulb.

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.
