In this guide, we'll show you what's included in your H3 LED headlight bulb conversion kit, how it all fits together, and how to install it with and without LED warning cancellers (anti-flicker).
Some vehicles have very small assemblies or little room behind the assembly due to other car parts being very close to the back of the assembly such as a radiator, backing plate, etc. In such cases, the LED bulb's fan might not clear, and installing any LED bulb will not be feasible for these vehicles.
As per our Terms & Conditions, given that LED bulbs contain extra components not found in halogen bulbs (including but not limited to micro-fans, drivers, etc.) some vehicles may not have the clearance to host an aftermarket LED bulb. It is the customer's responsibility to ensure that installing an LED conversion kit is feasible before ordering.
Please contact us to return your order if your vehicle cannot accommodate LED bulbs.
If your LED headlights bulbs are not turning on, please visit our LED Troubleshooting Guide.
Yes. The clear glass lens is only there to protect to bulb's diodes during shipment. If the lens cracks or shatters during shipment, simply remove it and proceed with installing your LED lights.
To remove the clear glass lens, simply unscrew the metal cap at the top of the bulb and slip off the lens. You can keep the cap off or put it back on, it makes no difference to the light output.
If your LED headlight bulbs have a cracked or broken clear glass lens, please see the answer to the question above.
If your LED bulb is damaged in a different way such as missing LED chips, damaged or broken stem, damaged, or broken fan, please contact us so we can replace the bulb(s) for your free of charge.
Some vehicles have a special mechanism to hold and secure the bulbs within the headlight assembly. This is occasionally found on some German cars such as Mercedes-Benz and BMW and from time to time in Korean cars such as Hyundai and Kia.
Most of the time, the original mechanism will not fit over an LED bulb and as such, you will need to get one that will fit over the LED bulb. They are extremely cheap and easy to find on eBay and Amazon.
As per our Terms & Conditions, adapters/retainers/clips may impact installation and fitment and are not included in our LED headlight bulb conversion kits. It is the customer's responsibility to acquire said adapters/retainers/clips and to ensure they are compatible with our LED bulbs and products before ordering.
Some vehicle headlight assemblies are sealed off with a dust cap, dust cover, or headlight cover to prevent dust, moisture, humidity, etc. from entering the assembly.
Although these covers generally fit over our LED bulbs just like for halogen bulbs, they don't for certain vehicles with very small or tight assemblies.
Since our LED bulbs do a great job of insulating the inside of the assembly, it is safe in the majority of vehicles to keep these covers off. If your vehicle is very low to the ground or exposed to high levels of water, mud, moisture, etc. you can purchase an oversized cap that will fit over the LED bulbs on eBay or Amazon for very cheap.
As per our Terms & Conditions, given that LED bulbs contain extra components not found in halogen bulbs (including but not limited to micro-fans, drivers, etc.) some vehicles with a smaller headlight or fog light housing and/or dust covers may require minor modifications to complete the installation. It is the customer's responsibility to ensure that installing an LED conversion kit is feasible before ordering.
If your LED bulbs are flickering or strobing, it is most likely because you require a warning canceller / anti-flicker or because of Daytime Running Lights (DRL's).
An LED warning canceller (also known as an anti-flicker or capacitor) is an accessory required on some vehicles to prevent your headlights and fog lights from flickering (strobing) and to eliminate the dashboard warnings normally caused by aftermarket bulbs.
The warning canceller bypasses your car’s computer system so the aftermarket LED bulbs can function properly. If your car requires a warning canceller but it is not added to your order, our LED bulbs will not work at all or as expected.
Warning canceller is required on the following vehicle manufacturers:
Acura , Audi , BMW , Cadillac , Chevrolet , Chrysler , Dodge , Ford , GMC , Honda , Infiniti , Jeep , Lexus , Mercedes , Mini , Mitsubishi , RAM , Volkswagen , Volvo.
