Volkswagen Passat B7 Upgrade with P21W Canbus Led Turn Signal Light

232 Published by Ava 10 31,2018

Volkswagen Passat B7 have OEM Valeo headlights with the beautiful beam pattern that offers a long distance lighting vision at night driving. At the same time, DRL, rear lights/brake light has nice performance and quality as well. However, the brightness of the turn signal light is not enough. The turn signal light of B7L should be designed to be LED strip light, but Passat B7 still housing with factory halogen bulb.

 

We use turning light frequently when driving a car. If the turning light using with a LED bulb which is made in high brightness, stable and fast start light source, it would be easier to get the pedestrians and driver’s attention whatever driving at daytime or nighttime on road. Especially, in highway or in the rainy and foggy day, we usually use turning light when changing the lane or use the light in double flicker when we intend to reduce the driving speed. Many LED turn signal lights are eye-catching and fast on/off which is beneficial to get the rear cars’ attention, if the turning light is not enough obvious to be noticed, there will be a risk of rear-end collision.

 

So, we have the reason to change the Volkswagen Passat B7 halogen turn signal light bulb into the LED light bulb. Our P21W canbus led turn signal light is developed for aftermarket replacement. Housing with 66*2016 SMD and stable light source that can reach 700 Lumens, it is double brighter than the halogen bulb. The power of this series led bulb is 23W, which is almost equal to the 25W halogen bulb, so it can simulate the operating current of the halogen bulb, don’t need to work with a load resistor anti hyper flash. The installation is very easy, plug and play.


The result of changing LED turn signal light are as below:

Are M3 Halogen Size Led Headlight Bulbs worth buying? (Test & Review 2019)

M3 led headlight was launched on March 2019. it is a high performance led headlight with High-speed turbo fan, the high beam led bulb is housing with 12 pcs Lumileds ZES chip and low beam led bulb has 6 pcs of Lumileds ZES chip. The maximum light output of M3 led bulb can reach 5000 lumens (a set of led headlight). Its appearance is close to the halogen bulb. M3 series bulb is housing on a 1.5mm extremely thin copper PCB board with opposing LEDs on two sides that decrease the distance between two side LEDs. With this special design, it can make the thickness of the light source close to the tungsten filament of the halogen bulb. Emitting ECE/DOT standard light beam pattern in reflector headlight housing without any dark spot. The M3 headlight equipped with a high-speed cooling system, which can make the bulb body in a stable condition with a 1300 rpm fans. It is easy to install as well, that would not influence to mount the dust cover. The bulb of M3 used 6003 Aluminium al...

What is a good headlight beam pattern? (DOT/ECE)

Standards for Headlight Beam Patterns -- edited by Kevin   This article will discuss headlight beam patterns and the standards that agencies such as ECE/DOT require. The following points will be addressed to help gain a better understanding:   1. What does the original ECE front headlight testing graphic look like? 2. The original ECE front headlight testing graphic combine with driveway image 3. Some testing points that need to pay more attention to 4. Other standards used in other countries and areas (SAE/ADR)     How do we define a safe and effective headlight beam pattern and what are the standards it has to meet? Most people would say they want a headlight that is super bright, covers a large area in front of the vehicle and has uniform illumination with no dark spots. But can this be achieved and still meet the standards set forth by ECE (E-mark) or SAE (DOT)?   The short answer is, YES! The keys to optimal performance are to be sure the light is focu...

2018 M2 Compact & Ultra Bright LED Headlights Review Guide

This is our new M2 LED Headlight series launched on November 2018. Its single beam housing with 2 pics CR CSP led chip while the dual beam housing with 4 pics leds, M2 led headlight kit can reach 6000 Lumen output. With an advanced dynamic design, high counterclockwise and low vibration of the fan, the M2 LED Headlight to work out the issue of noise in a safe situation.   The bulb of M2 used 6003 Aluminum alloy, and bulb body is integrated by the hot-pressing process for better heat dissipation. And it is using double layer copper PCB which provides a good heat dissipation. Because of the high adhesion between the double layer copper PCB, it is beneficial to the heat dissipation and extends the lifespan of LEDs, the LED chips would not burn out easily.     All in one style, the length of the bulb body is 77mm, the width of the heat sink is 31mm. The compact bulb body is close to the halogen bulb size LED Bulb Operating Temperature Testing Testing the led bulb with 1...

Are F2 LED Headlights Worth buying? (Test & Review 2018)

F2 led headlight was launched on September 2017. it is a high performance led headlight with fan, the double beam led bulb are designed with 4 CR CSP led chips while single beam led bulb has 2 pcs of CR CSP LEDs. The maximum light output of F2 led bulb can reach 6000 lumens.   The F2 bulb is housing one PCB board in middle with opposing LEDs on two sides that decrease the distance between two side LEDs. With this special design, it can make the thickness of light source close to the tungsten filament of the halogen bulb.   The F2 headlight using a small size fan is easy to install which would not influence to mount the dust cover. The bulb of F2 used 6003 Aluminium alloy with a decent surface treatment that creates a good texture for the bulb. Its operating power can up to 36W which will have a better canbus performance than the common 25W led headlight.     Next, we test the F2 led headlight performance, the reviews are shown as below:   LED Bulb Operating...

Fiberglass PCB vs. Aluminum PCB vs. Copper base PCB vs. Ceramic PCB

For the PCB boards now in application to LED headlight, there are mainly four kind of materials, Fiberglass(FR4) PCB, Aluminum PCB, Copper PCB and Ceramic PCB. It is a good deal to understand the distinctions for these four types PCB. Which PCB you choose depends on the circuit design construction of the headlight. FR4 vs. Aluminum PCB   Price Comparison In the cost comparison, the Aluminum PCB is more expensive than FR4, as well as more superior in performance.   Thermally conductivity Aluminum PCB has a great capability of thermal conductivity than FR4 which makes them play an important role in LED lighting technology.   Technology practices The thermal conductivity dielectric material of Aluminum PCB is a thermal bridge that connects the components and metal plate. It can transfer heat to the heat sink through the core automatically. An Aluminum backed PCB is assembled with aluminum backing, highly thermally conductive dielectric layer and the standard circuit lay...

Genuine G7 PK Fake G7 – How to Reduce Product Cost?

I think many people will meet this situation while shopping two similar products but with a great difference on prices.it is hard to make a choice for you, because you want to purchase the cheaper one but also worry about its quality as well. It is saying that you get what you pay. This is the best description of the current electronic products industry condition in China. Even high-value product like the laptop, or a cheap product like power bank or led light, we can find many similar products from different manufacturers. How can we identify which one is good and which one is in bad quality? We should take the product shell apart to see what kind of electronic component they used inside. In this way, we can understand the reasons why the suppliers always say that the price they offered is the best price and couldn’t be low, while another supplier can casually offer you a price cheaper 5USD, or 10USD.
