Decoding the Markings on Your Car Light Bulbs
Are you ever curious about the meaning of the markings on your car light bulbs? You may upgrade or replace your bulbs with confidence if you know what these markings mean. The meaning of these codes will become more apparent to you after reading this tutorial. Now, let's go into the intriguing realm of car lighting!
Manufacturer's Name or Logo
The manufacturer's name or emblem is the first thing you will see on the bulb. In order to recognize the brand and make sure you buy a high-quality product from a reliable supplier, this information is essential.
Voltage Ratings
The lightbulb's rated voltage is indicated by the numerals 6V, 12V, or 24V in accordance with ECE (Economic Commission for Europe) Regulation 37. These figures are crucial for determining whether the lightbulb is compatible with your car's electrical system. For instance, a 12V lightbulb should be utilized with a 12V electrical system.
International Category Description
ECE-standardized bulb international category descriptions are represented by symbols such as H1, H4, H7, and P21W. These codes represent particular bulb kinds and wattages, such as a 55W H7 headlight bulb for your car.
Country of Approval
The country in which the lightbulb has been tested and approved is indicated by the letter "E" followed by a number (for example, E1). Germany is represented by "1" in this instance. This data aids in determining the regulatory requirements that the lightbulb underwent throughout the testing procedure.
DOT Approval
DOT is an acronym for the US Department of Transportation. This federal agency establishes safety regulations for automobiles and their parts, including lightbulbs. A bulb bearing the "DOT" mark is authorized for use in the US market.
UV-Reduced Bulbs
The letter "U" denotes that the lightbulb is UV-reduced, per ECE requirements. These bulbs are made especially for use in headlamps with plastic cover lenses, which lowers the possibility of UV radiation damage.
Approval Mark
The bulb bears an approval mark given by the relevant authorities. Usually, it is composed of a mix of letters and numbers, such as 37 R (E1) + a five-digit number or just (E1) + a three-digit number. This code provides information on the bulb's regulatory compliance and the testing authority—such as the Federal Department of Motor Vehicles in Flensburg, Germany.
Manufacturer's Coded Mark
The letter "U" denotes that the lightbulb is UV-reduced, per ECE requirements. These bulbs are made especially for use in headlamps with plastic cover lenses, which lowers the possibility of UV radiation damage.
Mandatory Markings
The legislature only mandates that the following mandatory information be shown because of space restrictions on some bulbs: Manufacturer, output, inspection tag, and approval mark. These sparse indications guarantee that the consumer has access to important information about the lightbulb.
How To Choose the Perfect Car Light Bulbs
When purchasing automobile light bulbs, consider energy economy, color temperature, and brightness. The correct lightbulb can help you conserve energy and lower your energy expenses while improving the look and performance of your car. Knowing the marks on your car's light bulbs will help you choose the ideal option for your automobile, whether you require headlights, tail lights, or interior lighting.
