Frequently Asked Questions

Use our Vehicle Lookup Tool to search by year, make and model.

Vehicle application information should be used as a reference. Vehicle manufacturers may use different headlight assemblies or bulb types within the same year and model, so we recommend confirming the original bulb type before ordering or installing a replacement.

If your vehicle is not listed, please contact us for assistance.

The appropriate LED bulb depends on several factors, including the original bulb type, headlight housing, available installation space and the vehicle's electrical system.

LUMENS offers a range of LED headlight bulbs designed for different vehicle applications and lighting requirements. The right choice depends on factors such as bulb size, available installation space, and the vehicle’s headlight configuration.

Use our Vehicle Lookup Tool to identify the bulb size and any additional installation parts listed for your vehicle.

A projector headlight normally has a visible round lens in front of the bulb. The bulb itself is positioned behind the projector lens and is generally not directly visible from the front of the headlight.

A reflector headlight uses a reflective bowl to distribute the light. The bulb is generally visible when looking into the headlight assembly.

Bulb design and LED positioning can affect the resulting beam pattern, so choosing a suitable LED product and properly orienting the bulb are important.

Manufacturers may offer different headlight systems on the same vehicle depending on trim level, option package, production date or original lighting equipment.

When more than one bulb size is listed, compare the listed options with the bulb currently installed in the vehicle before ordering.

No. The Vehicle Lookup Tool is provided as a reference to help identify commonly used bulb sizes and installation components.

We recommend confirming the original bulb type before ordering or installing a replacement. Physical space, headlight configuration and vehicle equipment can also vary.

Many halogen applications can be converted to LED, but compatibility depends on the vehicle, headlight assembly and electrical system.

Some applications are straightforward, while others may require bulb holders, Smartboxes, harnesses, resistors, dust covers or other installation components.

Check the Vehicle Lookup Tool and the applicable product information before installation.

Many applications are relatively straightforward to install, but additional components may be required depending on the vehicle.

Modern vehicles can monitor headlight circuits in different ways, and some headlight assemblies use specialized bulb holders or have limited installation space. Check the Vehicle Lookup Tool for application-specific information.

Some vehicles monitor the electrical characteristics of the original lighting circuit. Installing an LED bulb changes the electrical load and can cause symptoms such as:

• Bulb-out warnings
• Flickering
• Lights switching on and off
• Other lighting-related compatibility issues

A LUMENS Smartbox may be used in certain applications to help resolve these issues.

A Smartbox does not correct every type of electrical compatibility issue, and additional components may be required on some vehicles.

Certain vehicles require additional components when converting from the original lighting system to LED.

Depending on the application, a resistor or harness may be required to address vehicle monitoring systems, daytime running light circuits or other electrical characteristics.

Because these requirements are vehicle-specific, refer to our Vehicle Lookup Tool and LED installation information before selecting additional components.

It depends on the vehicle.

Some vehicles operate the headlight bulb at reduced voltage or use other electrical methods to provide daytime running light functionality. This can affect the operation of an LED conversion.

Additional components may be required for certain DRL applications.

First confirm:

• The bulb and all connectors are fully seated
• The correct bulb type has been installed
• Any required drivers, Smartboxes, harnesses or other components are connected correctly
• The vehicle's related fuse is functioning
• The original lighting circuit is operating correctly

If the problem remains, test the bulb on the opposite side of the vehicle where practical. This can help determine whether the issue follows the bulb or remains with the vehicle.

Start by checking all electrical connections on the side that is not operating.

Where practical, swap the left and right LED bulbs or components. If the problem moves to the opposite side, the issue may be related to the bulb or component that was moved. If the problem remains on the same side, the vehicle wiring, connector, fuse or another vehicle-specific condition may need to be investigated.

Flickering can occur when the vehicle's lighting control system is not electrically compatible with the LED conversion.

Depending on the vehicle, a Smartbox, harness, resistor or other application-specific component may be required.

Check the Vehicle Lookup Tool and applicable installation information for your vehicle.

Some vehicles monitor the electrical load of the original bulb. Because an LED operates differently from a halogen bulb, the vehicle may interpret the change as a failed or missing bulb.

A Smartbox or other application-specific component may be required to correct the warning.

Yes. Proper LED chip orientation can be important for achieving the intended beam pattern.

For LUMENS LED products with an adjustable or clockable base, follow the applicable installation instructions when positioning the bulb.

After installation, always verify the resulting beam pattern and headlight aim.

Installation space varies between headlight assemblies.

LUMENS offers universal rubber dust covers in several sizes for applications requiring additional clearance behind the bulb. Confirm the dimensions and available space before selecting a replacement dust cover.

Do not leave a headlight assembly improperly sealed, as moisture and contaminants can enter the housing.

Colour temperature describes the appearance of the light and is measured in Kelvin (K).

Lower colour temperatures generally appear warmer or more yellow, while higher colour temperatures appear cooler or more white to blue.

Refer to the individual product specifications for the colour temperature of a particular LUMENS product.

Lumens are a measure of light output. Watts measure electrical power consumption.

Wattage alone does not indicate how much usable light a headlight will produce. Bulb design, optical alignment, headlight housing and beam pattern also affect lighting performance.

This varies by product.

Some LUMENS products are sold individually to accommodate vehicles such as motorcycles, snowmobiles and ATVs that may only require one bulb. Other products or accessories may be packaged differently.

Always check the product title, description and package contents before ordering.

CAN bus is a communication system used by many modern vehicles. In lighting applications, the vehicle may also use electronic monitoring to detect the operation or electrical load of a bulb.

When a halogen bulb is replaced with an LED, the different electrical characteristics can sometimes cause bulb-out warnings, flickering or other compatibility issues.

Additional installation components may be required depending on the vehicle.

Warranty coverage varies by product. Refer to the applicable product page or accompanying documentation for the warranty period that applies to your product.

Warranty procedures also depend on where the product was purchased.

Contact LUMENS HPL before returning the product.

Please have your order information, product information and a description of the issue available. Photographs, video, installation information or return of the product may be requested to help evaluate the issue.
