The 5202 LED fog light bulbs are a popular bulb type found in newer vehicles. They’re similar to 2504 bulbs but have a different set of alignment tabs on the base. These bulbs feature a high-powered Philips Z ES LED chip, which produces a precise beam pattern that increases visibility. They also have excellent heat management. This means they don’t require a fan to stay cool, which eliminates annoying noise and dust build up inside the housing.

High Power LEDs

High power LEDs are light-emitting diodes that operate at currents of hundreds to thousands of mA, producing hundreds or even thousands of lumens. They are used in industrial facilities, sports venues and outdoor lighting applications. Because these devices draw more power than typical LEDs, they generate a lot of heat, which needs to be managed. The most common approach is to use a metal PCB for heat dissipation and cooling, but a whole housing can also be used for this purpose.

In the case of high-power LEDs, ceramic substrates are often used as they are better in thermal conduction than plastic ones and they can withstand much higher temperature levels. They are also optically and chemically inert, making them a perfect choice for the packaging of high power LEDs. In addition, high power LEDs can be designed with an integrated cooling system that actively manages the LED’s temperature. These systems consist of a driving pump, a cold plate and a fan-cooled radiator that circulate liquids such as water or liquid metals to absorb the heat generated by the LEDs.

Integrated Cooling System

The 5202 LED Fog Light Bulbs use a unique integrated cooling system that keeps the bulb cool without requiring bulky heat sinks. A high-speed cyclone fan sucks air into the body of the bulb, then blows it out on the other side of the bulb. This enables the bulb to stay cool and resistant to snow/ice buildup on the lens. The bulb uses the latest newest CSP LED chips to produce more than twice as much light while cutting power consumption to a third of halogen bulbs. They also feature a long crystal over the entire diode array, which produces a smooth beam pattern that is perfect for fog lights.

They are designed to be extremely compact and fit most housings with a dust shield cover easily. The mounting depth is 20-25mm and the heat sink / fan diameter is only 39mm, making it possible to install these bulbs in most vehicles. These LED bulbs replace halogen fog lights. They are not street legal in the USA for headlights or fog lights, but they can be used on a variety of off-road applications such as Snowmobile and ATV headlights and off-road racing.

Wide Compatibility

Unlike H11 and 2504 fog light bulbs, 5202 LED Fog Light Bulbs are not universally compatible with every fog lamp housing. Despite the same locking tabs and plugs, there are slight differences in their alignment tabs on the base, which makes them non-compatible for many different vehicles. Nevertheless, there are several common types of these popular fog lights that are known to work on most cars and trucks. They are commonly used in many newer vehicles such as the 2014-2018 GMC Sierra, 2018+ Jeep JL Wrangler, and the 2013-2017 Subaru BRZ among others.

These bulbs are available in both 5000K and 6000K color options. You can select the option that better suits your car or truck’s color scheme and/or the weather conditions you drive in. They are the perfect choice to enhance your vehicle’s headlight and fog light appearance while preserving their proper function and sharp, focused beam performance.

Long Lifespan

LEDs are more durable than halogen and HID bulbs and last much longer. Typically, an LED bulb will last 50,000 hours or more of use, as opposed to a halogen or HID light that typically has a life cycle of around 400 hours. In addition to being more durable, LED fog lights are also a lot more energy efficient than other lighting options. These bulbs use up to 85-percent less power than quartz halogen or high-intensity-discharge (HID) lights, saving you money in the long run on fuel and energy costs.

Designed with the latest Philips Z ES chips, Sea light’s 5202 LED fog light bulbs create about 2 times as much light at less power consumption than your original halogen bulb. They don’t require a fan mounted to their heat sink and feature advanced thermal management to ensure up to 50,000 hours of reliable performance.

Last Word

Upgrade your original halogen fog lights to the brightest & most efficient LED bulbs on the market. With superior lighting beams & longer lifespan, your new bulbs will improve your visibility & safety while driving at night.
