LED bulb WR21W-7440 VENTIRAD XS (Red)
New Generation of Powerful Red LED, Best Anti-error LED highly recommended for BMW, Mercedes, VW…
Satisfaction guaranteed!
The WR21W Ventirad XS is an innovative LED and the most high-performing in our range, designed for use: brake lights, rear fog lights... It adopts 24 new generation chips, Seoul technology (red color), perfectly arranged as close as possible to the center of the LED, allowing for multiplied red light output. Ultra-sophisticated, at the cutting edge of technology, the Ventirad XS is the 1st WR21W LED bulb equipped with a cooling fan, which allows it to be the best anti-error LED currently available (eliminates error indicators in 99% of cases).
An anti-error Can-Bus LED, ideal for all high-end vehicles (multiplexed system) equipped with a high level monitoring system, for example: BMW, Volkswagen, Audi, Mercedes, etc. With this LED, replace your brake lights or rear fog lights with the guarantee that you will not see any error indicator appear, even after several minutes of operation or after starting the vehicle, as may have already happened to you.
Easy to install, 100% Plug & Play
Install this WR21W LED Ventirad XS bulb as you would install a standard bulb: no modification is necessary, nor do you need to add a resistor to your installation or a specific relay, unlike a standard LED not equipped with a fan.
Why choose the WR21W Ventirad XS bulb?
Because it has perfect heat management thanks to its built-in fan, a major asset that allows it to maintain a very high level of stable performance (1004 lumens peak record in its category). But that's not all: apart from stabilized performance, the ventilated system also allows for better neutralization of OBD errors. Indeed, the XS cooler is capable of reaching and maintaining an electrical consumption value (2 A) identical to the consumption of your original P21W bulb, without any decrease in consumption, unlike a standard LED. This aims to perfectly trick the electrical system of modern and high-end vehicles. Thus, your vehicle's electronics will not detect a burnt-out bulb, because the power consumption of this LED will be the same as that of your original bulb.
The end of the puzzle
No more compromises from the past between LEDs with built-in resistor or LEDs without resistor. Below, here is an explanatory link to learn how to differentiate the different WR21W LED technologies (without resistor and with resistor) and their uses.
Choose the comfort and safety of a WR21W Ventirad XS equipped with its ventilated cooling system. It alone brings together the best of LED technologies with built-in resistor (high-performance anti-error system and high power) as well as the best advantages of resistorless LED technology (very reliable LEDs, emitting little heat, capable of operating for several hours).
Advantages :
• Recommended for all uses: brake lights, rear fog lights, etc.
• LED equipped with the most efficient anti-error system in our entire range, eliminates error indicators in 99% of cases, even after several minutes of use. Ideal for vehicles equipped with multiplexing: Audi, Volkswagen, BMW, Mercedes…
• Restores the normal operation of your bulbs: a common example observed on BMW and modern cars, after installing a standard LED, the bulb does not work at all or only for a few minutes before stopping. With the WR21W ventirad XS, this problem will be solved.
• Perfect heat management, which makes it very reliable and safe for your installations.
• The most efficient and stable of our entire WR21W LED range.
• 100% Plug & Play installation very easy, just as you would with your original bulb, without any modification.
