There is more to fog lights than just an aftermarket lighting accessory. Automotive brands, distributors, retrofit companies, and vehicle modification businesses have the opportunity to improve vehicle visibility and create a product that accommodates vehicle models, market needs, and brand identity by offering customized fog lights.
Custom fog lights involve much more than shape of the housing or light color. When a customer is thinking about developing fog lights, they have to consider many elements, including vehicle compatibility, optical performance, electrical specifications, materials, appearance, and packaging before they can move to production.
We have simplified the custom fog light development process into these main steps.
1. Define the Vehicle Scope
The starting place is to define which vehicles the fog lights would be made for.
Different vehicle models can have dissimilar bumper structures, differing layouts and positions of mounting locations, different connectors and types of installation, and different electrical systems.
Before kicking off a custom project, buyers would typically provide the following:
- Vehicle brand and model
- Year of production
- Original fog light size
- Mounting structure
- Connector type
- Voltage
- OEM part number or equivalent
For replacement fog lights, accurate vehicle and model compatibility is critical because even a slight difference in dimensions can affect installation.
2. Choose a Fog Light Type
The next selection is the fog light system.
LED fog lights are very popular as they allow for compact construction, high light output, long life, and great design flexibility.
Depending on the project, buyers are able to customize the following:
- LED fog lights
- Projector fog lights
- Driving and fog light combinations
- Fog lights with daytime running lights
- Fog lights with sequential turn signals
- Multi-function auxiliary lights
The ideal configuration will depend on the target vehicle and how the product will be positioned in the market.
3. Define the Optical Performance
Brightness is relatively easy to achieve, but the best fog lights create a controlled beam pattern over simply producing a brighter light.
In the presence of fog, normal light reflections scatter back into the driver’s field of vision. For safe visibility then, the beam pattern, reflector design, cut offs, lens design, and placement of the LEDs all come into play.
During the planning process, buyers can specify the following:
- Lumen output
- Beam pattern
- Color temperature
- Light distribution
- Lens and LED configuration
- Driving and fog light functions
A competent Fog Lights Manufacturer can match these components with the intended vehicle application and target market.
4. Select the Housing and Lens Materials
Durability and appearance are both concerns with the placement of fog lights as they are close to the road surface where they’ll encounter water, dust, heat and vibration, as well as mud and stone impact.
Material selection may focus on:
Housing Material
Housings made from aluminum alloy may improve heat dissipation, while housing made from engineered plastics may help control manufacturing costs.
Lens Material
Depending on the product design, manufacturers may consider using polycarbonate or other automotive grade transparent materials.
Sealing structure
Well designed sealing prevents moisture and dust from reaching the internal components of the LED and the optical devices.
5. Customize Appearance
Appearance of after market products may be important to some buyers.
Fog lights can be designed to either match the vehicle design or complement a custom built vehicle.
These fog lights can utilize exterior design features such as:
- Form factor/shape (i.e rectangular or round)
- Lens material (smoked or clear)
- Housing color (i.e silver or black)
- A DRL strip
- Custom Bezels
For many customers, the fog lights act as a way to distinguish the vehicle from competitors.
6. Verify the Electrical Specs
Prior to mass production or tooling, the electrical compatibility should be confirmed.
Specifications of interest could include:
- The voltage (12V or 24V)
- Power draw
- The configuration of the wiring
- The structure of the connector
- CAN bus compatibility
- Polarity
- The configuration of the driver
Some automobiles will cause the dash to light up the warning systems after the use of aftermarket lighting products. In those cases additional electronic solutions are needed.
7. Add Branding and Custom Packaging
Additional customizations are available outside of the fog light.
Distributors and private-label clients often ask for:
- Logos
- Labels
- Model name
- Manuals
- Packaging
- Custom branded cartons
- Retail packaging
- Barcode label
- Solutions
Branding is important because it helps differentiate automotive lighting products.
8. Sample Development and Testing
Samples are highly encouraged prior to mass purchase of any fog light.
With samples, the customer is able to evaluate:
- Design aesthetics
- Construction and materials (ie. are the lights waterproof)
- Performance
- Beam patterns
- Potential issues with the connector or fit
- Quality of the fog light housing
- Packaging
For vehicle specific equipment, installation is recommended on the host vehicle to evaluate the fog light.
After market solutions are used to make modifications to the lighting before mass production.
9. Consider the Testing and Market Needs
Automotive lighting needs vary from country to country and market to market.
Buyers need to consider regulations, certifications, and the required electromagnetic compatibility, environmental testing, and product marking. Depending on where fog lights will be sold, there are many factors to consider.
Testing of a typical product may include:
- Testing for waterproofness
- Dust resistance
- Anti-vibration
- Temperature
- Lighting output
- Electrical stability
- Aging performance
Buyers should inform the manufacturer of the destination of the market in order to conform to necessary regulations.
10. From Prototype to Mass Production
Once a sample is approved, the manufacturer can prepare for mass production.
A common process may be:
- Design Confirmation
- Prototype Development
- Fitment Testing
- Performance Testing
- Sample Approval
- Mass Production
- Quality Inspection
- Packaging and Shipment
Consistency is crucial to maintain specifications of the mass produced fog lights and the approved sample. This is especially important to vehicle specific lighting product replacements.
Final Thoughts
The successful integration of customer fog light demands a compromised approach on vehicle fitment, optical performance, durability, electrical integration, and styling within cost constraints.
Detailed information of the vehicle and product requirements given from the outset of the project by distributors, automotive lighting brands, and aftermarket companies reduces the number of revision cycles. Focusing on the entire system of fog lights, not just brightness and looks, leads to a reliable aftermarket product for replacement devices through careful design and consistent manufacturing.
